Yealink CP965 and UVC50 flip camera upside down?

Hi Community,

I have a new Yealink CP965 that is connected to a Yealink UVC50 camera using Zoom Rooms and this is a controller. 

We have the camera mounted upside down due to the physical layout (not my decision). The old phone they had was able to flip the camera but I cannot find any method on this model. There is a mirror function but that is left to right. Any help is appreciated.

Thank you,
