This is not really what you're looking for, but maybe it could be a part of the solution:
- This could be used to set the FoV using a trigger:

FieldOfViewController.cs )
- If you want to to be on scene load, or on VaM load, you just need to find a plugin that will set the right value, something like
https://hub.virtamate.com/resources/scripter.30210/ could work, or you could use a keyboard shortcut using
https://hub.virtamate.com/resources/keybindings.4400/ etc. (I'm sure there are other solutions, those are the ones that I can easily think of)
