Most games with anti-cheat refuse to run on Linux even if the anti-cheat itself supports it. And some anti-cheats just don’t work on Linux anyway, I believe the ones that do only support it by just not running when they detect they’re on Linux. If you’re interested you can check which games are supported here: https://areweanticheatyet.com/ but bear in mind it could change at any time (for example Rockstar broke GTAV a few weeks ago)
