Have widget take up whole screen when in landscape mode

I’m using OrientationBuilder to change my screen in landscape. Currently in portrait my widget sits on a Botton Cupertino Nav bar. I want to get rid of my bottom nav bar when the phone is in landscape mode. I’m not really sure how to get rid of it…since it’s quite nested. I suppose I maybe looking to have a new navigator in landscape .. But not sure how I would do this in the builder
