I made a Timeshift backup of my system, as well as a system image backup, and now I would like to see what things look like if I uninstall all the EOS/endeavouros packages.
How to do that?
Remove package
sudo pacman -R PROGRAM
Remove package & unused dependencies
sudo pacman -Rns PROGRAM

To list installed packages from the endeavouros repo:
pacman -Sl endeavouros | grep installed
Then do what keybreak suggests:
sudo pacman -R package01 package02 package03 ...
Alternatively, do both of the above commands at the same time:
sudo pacman -R $(pacman -Sl endeavouros | grep installed | cut -d' ' -f2)
When you’ve removed all packages from the repo, check than none remain with the first command. Then you can edit your /etc/pacman.conf and remove these three lines:
[endeavouros]
SigLevel = PackageRequired
Include = /etc/pacman.d/endeavouros-mirrorlist
And then update:
sudo pacman -Syyu
BTW, you’re still not using Arch, as defined by the people on the Arch Forum – that requires you to install it the Arch WayTM

The one-liner needs also package eos-bash-shared.

Getting there…
I did the above and reinstalled grub and rebooted.
but inxi and grub still think I am running EOS, although I don’t see any EOS theming or apps.
If you want to change that too, the answer is in the post you marked as solution here

Thanks to all for your help in this experiment. Now, after removing it, I appreciate how good the EOS theming is. 
And EOS also provides certain basic tools that I would immediately install in any case, such as inxi .
Grub gets is OS name from a line in /etc/default/grub.

Thanks. I discovered that the no-brainer way to change the grub name is with grub-customizer
You need to reinstall the packages filesystem, lsb-release and probably grub after removing the EOS packages.

Now I am reversing the changes I made I added EOS back to pacman.conf

# The header [repo-name] is crucial - it must be present and

But something is not right because when I run
sudo pacman -Syyu
it is not getting the EOS packages:

Or maybe it is the fault of my proxy?
As said above, remove these 3 lines:
But removing those three lines is what I did when I converted to “pure” Arch. Now I want to return to EOS. How will I get EOS packages without those lines? 
You won’t.
But this looks like your endeavouros-mirrorlist from /etc/pacman.d is not quite well.
Use this:
