Hey guys, anyway to disable my Fn key on my desktop computer?

A lot of games I play, I set F1 to change from first to third person view, and it's really annoying to have to press Fn + F1.

I know, total first world problem, but I'd love it if I can get some advice on this? Google brought up results for laptops from what I saw in the links I clicked.

Thanks a bunch guys.
