How do I manually add mods on the Steam Deck?

[DragonKnightKX]

I want to add a few mods to the game, like tRCM, the droid planet, the extended Enclave, and the Party swap mod. I read that I'd have to manually install them instead of using the Steam Workshop if I wanted multiple mods at once, but I don't know how I'd even go about installing them since, from what I can tell, the Steam version (the only one I have) only lets me download the Windows version from what I can tell, and I don't even know if the .exes for installing the mods would work on the Steam Deck.
