Automatic sitting guardian selection

Hi,

we are developing Oculus Quest app in Unreal. Basically we have a couple of Quest's set up in a bus with a mapped route. Passenger has a seat with Oculus, and when the bus starts moving, we capture movement with couple of sensors, and recreate movement in the VR world. Passenger seat is safe and they are buckled up. App runs in kiosk mode.
We have a problem, where we have to each time set up guardian system. Basically what we would need is an option to make guardian system default into standing siting mode, instead of constantly asking on boot to confirm the boundaries. Since the passengers are in their seats and buckled up, whit oculus set up in a way that can be used only in the chair, there is no need to recheck for guardian each time.
Can we some how make this a default thing

Thank you
