How do i change FOV in a vr script?

Hi, so im making a vr script. (based on a mag agent from Madness Combat) the problem is that since the mag agent is apparently 2.5 times bigger then a normal player

the hands and head are limited in space and you cant move around much apparently you cant change fov in VR or its just a error.

what ive tried: Setting FOV changing character size changing cameras CFrame

Script is private so i unfortunately cant put a code snippet anywhere. but if anyone can help me i will really appreciate it!
