I don't believe there is a viable path for kernel-level anti-cheat on Linux (thank god). What most developers have done is enable normal anti-cheats on Linux, even if they use kernel-level ones on Windows. This is the path they seem to be going down.

Ever since CrowdStrike, I'm a bit amazed Microsoft hasn't taken a hard stance on the gaping security hole that is kernel-level anti-cheat. It's bonkers such is expected or even allowed just to play a game.
