not sure where you check for mods. if its nexus, most mods explain how to manually install.
bepinex what i needed for alot of mods also explains how to use it with linux and is most of the time linked in the mods aswell.

bepinex is an open source project and safe to use
most nexus mods alsoif you are really paranoid wait for mods that got released like today.

but backup your saves like the others said.
the mods will probally not ruin your pc, but could break saves.
(didnt see that happen yet)
