I'm guessing this belongs in linuxgaming or similar.

As I understand the current intended implementation and constraints: no. Anything not signed with keys trusted by EACv2 will prevent it from running if loaded. Your MOK while fubctional for secure boot, won't be on the list of trusted keys. Additionally, if MOK-signed modules were allowed, it largely defeats the security model EAC seems to be expecting. Ultimately, if your distro's kernel is trusted by EAC, they would also need to either bundle or provide non-dkms signed builds of the kernel module you need.

My guess is it won't... Signed modules only, so since third party modules typically aren't... One can guess eac2 wouldn't allow it... I'm glad people will be able to play fortnite on Linux but near kernel anti-cheat is still a hard no for me
