Hide telemetry displays?

Hi, new user here, please be gentle!

I’m looking at buying a Herelink system to control my mast-mounted camera gimbal and display the feed from the camera. So, no PX4 involved, I intend to connect the Herelink air unit’s S-BUS output direct to the gimbal (FreeFly Movi).

So I’d really like to have the video feed from the camera occupy the entire screen on the Herelink, since I don’t need the map display or any of the telemetry panels. In advance of buying the Herelink I’ve been playing with QGC on a standard Android tablet, but I can’t find any way to get rid of the telemetry displays.

Any advice? Can it be done or am I on a wild goose chase?
