Is there an option to freeze or pause the VR headset? This is what I used with TIR. I mapped a button on my HOTAS so I could pause head movement. While it was paused, I mouse around over the switches and nobs, then quickly unpause the headset to go about my business looking around. Using the wands is not an option, and even if you have a button box, there are some things you need to do in VR.
To be clear, the pause mapping is an option in the TIR software. So it would probably have to be implemented by the VR hardware manufacturer? What a pisser.
