Oculus Quest Camera Acces / Experimental Guardian options?

Hi there! Im currently making an application in ue4 where the environment is generated by the guardian grid. So far its working well, but I was wondering if there was a way to get rid of the maximum of a 5*5 grid. Maybe as an experimental guardian feature? It would also be cool to 'cut out' a sofa or something thats in the middle of your playing field, to get more customization.
Another thing I would love to see is acces to the camera (maybe as a render target). I know im asking much, but if there are any workarounds, Id love to know. 
Thanks!
