I think you can play PvE Tarkov because the raids run on your machine (except for Streets). But if you’re already willing play PvE you might as well play SPtarkov which does work on Linux and has a modding scene that offers a significantly better PvE experience.
EDIT: just a PSA that Tarkov uses Battleye, which supports Proton. Just like with almost every other game the only reason you can’t play Tarkov on Linux is because the developer doesn’t want to you to do that.
