Bethesda games there is MO2 for linux.
Vortex can work really well on Linux and you can easily install it using steamtinkerlauncher.
For games like BG3 that have their own modding tool, you can run them using Wine/Proton.
You can also just mod manually like GTA3/GTA VC/GTA SA(I played these games on Linux, which is why I’m citing them).
Or you can use a tool made for Linux like Limo.
