4K powervu/biss NO RELAY / NO REBOOT - Satellite Receivers

Are there any 4K receivers that can watch powervu without RELAY and without a reboot when you watch Biss Channels?

I know the DreamBox 900/920 can, but have to reboot.

Are there any other 4K that work without relay and don't require a REBOOT when switching from PowerVu to Biss?

The Zgemma works without Stream relay?? I did not know that??

What image are you using on the Zgemma and does it support no relay out of the box, or do you have to install updated drivers??

Where did you buy it from?
