Custom "extreme" zoom out settings while remaining in cab view

Is there a way to zoom out the FOV in cab view beyond what's allowed with the mouse scroll wheel? Currently if I'm in cab view I can zoom out a little bit, but fairly quickly it flips to the outside view as it continues to zoom out. I'd like to have the option of continuously zooming out whilst remaining in cab view, essentially achieving a very wide angle of view within the cab itself. I'm trying to accomplish this to be able to use my Quest 2 headset in cab view; I have the other components in place, but I just need to be able to get the current field of view within the cab much wider than I've been able to accomplish up to this point.
