Only certain HP notebook computers come with Optimus technology. If your computer came with Intel IPG and NVIDIA Optimus graphics, HP has already preconfigured your system to work with Optimus. Most of the time, you do not have to do anything to use NVIDIA Optimus graphics.
You should try Kde. Install it and use the nvidia option on the live ISO. Then maybe we could go from there. Hyprland is a bit more complex and since this is a hybrid laptop it makes it even more so. But is entirely up to you. Also i would check that the UEFI Bios is up to date.
optimus-manager --switch nvidia
WARNING : no power management option is currently enabled (this is the default since v1.2). Switching between GPUs will work but you will likely experience poor battery life.
Follow instructions at https://github.com/Askannz/optimus-manager/wiki/A-guide--to-power-management-options to enable power management.
modinfo: ERROR: Module nvidia not found.
WARNING : the nvidia module does not seem to be available for the current kernel. It is likely the Nvidia driver was not properly installed. GPU switching will probably fail,
continue anyway ? (y/N)

Okay so i do know there have been issue with optimus-manager itself so maybe uninstall it for now. Then lets try installing nvidia the old fashioned way. Make sure you reboot first after removing optimus-manager.

Well installing nvidia manually would need the nvidia-lts and also the version for zen. So maybe since you have optimus-manager removed try installing nvidia again with the tool.
