[Request] Option for disabling unselected gizmo

I'm using post processing volumes for my water volumes, and it's quite annoying to have hundreds of green boxes everywhere. I know I can disable the entire gizmo for the volume type, but that's sort of a iffy way to do it I'd say.

Would it be possible to have a toggle that disables the gizmo that appears when not selecting it? Or even a field that scripts can access?

Thank you
