When facing the guardian limit and still having to go straight in a game I have to trick by physically overturning myself (VR & IRL) and in the mean time use the thumbstick to virtually overturn again (VR only) so that I can walk straight again and remain in my guardian area.

It would be more efficient to be able to temporarily fix the virtual orientation while I am physically reorienting in my playing area in a fast maner (I.e by simply pressing a combination of buttons)
