I believe that Vortex, the nexus mod manager, has Linux support now that I have heard is fairly straightforward but I haven’t tried it myself.

I will say though that I recently used Vortex for modding my Fallout 4 playthrough and it was a breeze on windows while using a Nexus mod collection. Takes a lot of the pain out of modding for sure. So if you can get their mod manager running I think it’s worth a try. Could be as simple as downloading Vortex, finding a collection of mods you like, downloading the collection (usually a temporary subscription is nice for this, and then running the game. You could be done like I was in a matter of a couple hours.
