How to fix gimbal yaw to aircraft yaw - POI

Hoping this is a simple one.
Using a Pixy F gimbal with mavlink control.

“point camera here” and “poi” works great in that the camera yaws and pitches to point at the target.

What I want to do is for the aircraft to yaw and not the camera, such that the camera and gimbal always remain aligned.

Struggling to find any parameter that has the desired effect. Is there a way of doing this?

You will need to ask Gremsy for that.
