Download OVR Advanced Settings from Steam (https://store.steampowered.com/app/1009850/?snr=1_5_9__205). Open OVR Advanced settings and navigate to the "Off Sets" tab.
Use the slider labeled "Rotate Space" and hit Apply. It might take you a few tries to get it just right.
Quest users be aware that any time you take off the Quest, use the Quests recenter function, put the Quest asleep, etc, it will generate new coordinates and you will have to run a LIV calibration again.
