I switched to EndeavourOS from Manjaro Linux which had mhwd as a driver manager, in that utility it had the option to install video-hybrid-amd-nvidia-driver-450x-prime which worked perfectly for my laptop. How would I do that same thing on EndeavourOS?
Laptop Asus TUF FX505DT.
Kernel 5.10.7-arch1-1
DE Plasma 5.20.5
CPU AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx (8) @ 2.100GHz
GPU NVIDIA GeForce GTX 1650 Mobile / Max-Q
welcome at the purple side of Linux!
We do not have tools from Manjaro here, but we have some wiki to a first read, and a friendly bunch of users will join to help here:
So try that first and if you are stuck or have any question ask we will be happy to help.
I looked into the wiki. Problem is I do not have an AMD dedicated graphics card, it is an nVidia one. I know you do not have the tools from Manjaro, that’s why I said:
Manjaro Linux which had
mhwdas a driver manager
you might want to re-read my question, I want to have a hybrid setup that would use integrated Vega IGP for most application but I want to be able to use prime-run to offload to the dedicated nVidia GPU. Thank you for the response!

If by what desktop you mean what DE, I listed it in the main post its KDE Plasma.
Edit: I tried running the nvidia-installer-dkms but after rebooting systemctl it gets stuck.
Currently it is running on Nouveau open source driver for Nvidia and AMDGpu.
Maybe you can try running the installer in test mode and see what info if any it provides.
nvidia-installer-dkms -t
This will run in test mode. See what it shows.

Looks like it should work, I did this before installing it initially too. I know for a fact that when I was using Manjaro Linux, it was also pulling nvidia-prime as part of the video-hybrid-amd-nvidia-driver-450x-prime driver.
You install prime after. Looks like no errors so I’m not sure what’s up with systemctl. You’d have to look at that after separately to diagnose.
If you want to install nvidia then
sudo nvidia-installer-dkms
Then you can install prime.
To install Optimus Manager.
yay -S optimus-manager-qt
To check if it’s running.
systemctl status optimus-manager
Edit: If it’s not running. To start & enable
sudo systemctl enable --now optimus-manager
Welcome @ferretwithaberet 
This might help too: https://forums.developer.nvidia.com/t/nvidia-xconfig-doesnt-do-what-i-want-it-to-nor-does-nvidia-settings/107883/7
This is where it gets stuck. Also, I do not think installing optimus-manager will work, because afaik this laptop is not considered an optimus laptop. The way it works as far as I got it is that it starts by using the IGP then offloads to the dedicated GPU, this being called “AMD switchable graphics”. I recall asking a dev of optimus-manager if I remember correctly, and he told me it does not support AMD-nVidia configurations, only Intel-nVidia or Intel-AMD.
Okay … if that is the case then Optimus manager may not work then.
Edit: If this is how it works then it should automatically switch to nvidia then. So why it’s hanging at the boot i’m not sure.
Edit2: I think this is something you are going to have to put some effort into diagnosing. Did you wait longer and see if it will boot past here?
Maybe this helps.
I did wait quite a substantial amount of time for it to load.
Edit: I also have no /etc/X11/xorg.conf file, it that is important.
Yes i think this is may be part of the reason or all of it.
Edit: You could try adding this.
sudo nano /etc/X11/xorg.conf.d/20-nvidia.conf
Add the following
Section "Device"
Identifier "Nvidia Card"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "NoLogo" "true"
EndSection
Section "Screen"
Identifier "nvidia"
Option "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"
Option "TripleBuffer" "on"
Option "AllowIndirectGLXProtocol" "off"
EndSection
Save the file.
I mean, I saw most “solutions” had a step that requires the user to remove that file anyway, so it might not, I really do not know. Manjaro was doing this for me so now I am left in the dark. 
Yeah, It does not seem to work. It gets stuck in the same place, without the nvidia driver the OS works flawlessly.
Well I would try the setup that i posted the link to above. Just to see as he is using two files one for the amd and one for the nvidia. Don’t give up too easily. 
Thing is, his config uses "OutputClass" while the default one uses "Device".
I’m not sure why but if you don’t try it i guess you won’t know.
Edit: This is the explanation i see.
The main difference is that Device sections are used for static configuration (e.g. “here’s the configuration for a specific piece of hardware”) while the *Class sections are used for dynamic configuration (e.g. "here’s the configuration for any device that has these properties).
