So, the problem with anticheat on Linux is there's no "safe" reference version of Linux that you can enforce to be running. This is a good thing. It's supposed to be modifiable. This fundamentally conflicts with the goal of anticheat which is to stop you modifying it. I predict they won't allow all Linux but only the specific version Valve puts on the Steam Deck/Machine, and if you modify it then your games won't run again.
