Do the kernel level anti-cheat windows only dev guys support steam deck running official steamOS?
Some games anticheat supports Linux. VAC, EAC, GameGuard, and BattlEye either run under Linux by default or can be configured to do so, by the game dev, with a toggle. A number: Destiny 2, Fortnight, etc. break it intentionally even though the client could run without modification. Battlefield 6 breaks because it checks the Windows measured boot API.
