UVC Camera Adapter Board V4l2 Controls

Hi,

I have a B0278 UVC - USB adapter board for raspberry Pi high quality cameras, and I cant get any camera settings to apply through the v4l2 controls. By camera settings I mean things such as exposure, brightness, white balance etc. I have tried this both on a jetson xavier nx (jetpack 4.6), and in ubuntu 20.04 running on a laptop.

The v4l2-ctl command line tool will report that these controls are present, and set properly (set both through the command line tool and opencv), but there is no effect on the image from the camera.

My main question is are these controls actually supposed to be supported by these adapter boards?
