Is there a solution to this other than just having a bare metal backup with windows or running games that use this in a Virtual Machine? I would love to be able to run Elden Ring with some friends but TBH I’m not comfortable with EAC just having it’s way on my Linux system.
Elden Ring has EAC support on Linux (https://areweanticheatyet.com/)
You have 2 choices:
- Play the game with friends (EAC involved)
- Don’t play the game at all (no EAC involved)
There ain’t no fun in using Easy Anti 
I’m always on a VPN, & that posted link won’t even let me onto the site to read about it.
So I just walk away (so to speak).
Welcome to the EndeavourOS forum. I hope you enjoy your time here.

Also:
- Play the game solo, (& with no player messages) (no EAC involved) by running eldenring.exe directly.
On a different note, I think EAC is much less invasive in Linux. Not kernel level at least.
I wonder whether it could be sandboxed to some useful degree, for instance with firejail, and still work.
AFAIK Elden Ring has a launch option for disabling EAC.
Not natively, but this
echo "%command%" | sed 's/start_protected_game.exe/eldenring.exe/' | sh
seems to work.
And for more options, I just tested this
echo "mangohud gamemoderun %command%" | sed 's/start_protected_game.exe/eldenring.exe/' | sh
which works a charm. It’s good because EAC has been giving me trouble for two weeks or so. Much more convenient than renaming the executables.
No friends, no anti cheats 
To be honest I play mostly story driven single players. The last multiplayer game I played was Insurgency Sandstorm and It was working fine with EAC.
