No. EAC and Battleye developed ways to explicitly support proton, which has to be explicitly enabled by the developer for the game to run.
Proton didn’t change, the popular AC options did. They’ve had proton support pretty much since the steamdeck launched, and it works great as long as the developer of a game bothers checking the checkbox for it.
EAC works on linux just fine, and the fact that Apex runs, means Respawn deliberately allows it.
