Anti-cheat is usually a kernel extension, I don't think you can do that in Proton. Edit: yes, I know EAC is Linux supported, but you can't use proton to run a Windows kernel extension.

It seems to be up to the developer, as many anti-cheat support Linux if the developer wants it to. Elden Ring uses Easy Anticheat which works fine in Proton, but Black Desert also uses EAC and it doesn't. Phantasy Star Online 2 works with Proton-GE and it used GameGuard and now Uncheater. Here's a crowdsourced list of games with anticheat that do or do not work with Proton: https://www.protondb.com/explore?selectedFilters=antiCheat https://www.protondb.com/explore?selectedFilters=antiCheat
