For Linux no, not for the last 15 years or so. For windows yes, still possible.

But AC is kinda useless on Linux anyway, might as well have none.

I don't think we're talking about the same thing, I was specifically referring to Epic Games' efforts to add effective AC to linux via secureboot + signed kernels + a kernel module + remote attestation

The entire point is to lock down a user's linux install so that they can't interfere with the anticheat.
