Disable boundary for MR apps

Hi, 

I have been messing around a big with creating an MR app with passthrough and the Scene API in UE5.2.1. One thing I have noticed is that even though the scene has been set up the user is still prompted to make a guardian when stepping outside the zone.

This however makes no sense as "First Encounter" works fine and has no guardian system in place.

How can we disable the guardian system for our MR application?
