Yes, please have a look at Mods for non-Steam players - #2 by BaYoNeTTe
If you see a mod on Steam that you like but that is missing on Nexusmods, then you can also ask in Discord if a Steam user can download it for you. Not sure if this is legally ok but I suspect nobody cares…
If you have a specific feature request you can also tell me. If I think it would make IS better than I may create a mod for it.
