All the games I've played with anti-cheat software under Linux, exclusively run in userspace.
That's (of the reasons) why you can't consistently determine which ACS work: those that support Linux have to make the compromise of not running in kernel space (let alone as root), and sensibly let the developer choosing whether to allow such compromise.

Would you like to engage in a polite and collected conversation about the YouTube Shorts UI?
Eh, userspace has some limitations that cheaters can circumvent more easily if they get their hands beyond it.
Kernel-space ACS is not going to stop you if you're motivated enough, though, and at some point it becomes more of a hassle to deal with for the legitimate player than it is for the cheater.
Like those websites/services with password requirements so insane it's actually difficult for you to cook up an actually good one.
