We desperately need a "Guardian" off toggle to permanently disable 6DOF and use gyro only 3DOF, identical to the function already available in the Quest 2.
We are using many Rift-S sets in a Mars Rover experience, but the experience is ruined as the dark environent triggers an error message.
The users are sitting in a chair using a joystick, and for most use-cases like this (stationary) the camera tracking function with 6DOF is not needed at all.
