Are you looking for games that don't use shooting (or a variant of "point camera at thing and press button") or games with no combat, or games that have combat but give you options around it?
There are plenty of immersive sims that allow pacifist stealth runs but that falls under "combat" broadly. Most Deus Ex games probably? There are RPGs where you could build a diplomatic character to avoid combat but there aren't many in the FPS era that I know of. Outer Worlds might allow it? Don't remember how possible it is in Fallout New Vegas, I know you can pacifist it but that might block off some content.
As for first person scifi RPGs that avoid any sort of combat altogether, there aren't any that I know of. Unless you're counting something like Tacoma, which I don't believe has living NPCs to interact with or character progression.
