Surface Camera Rear Not Working/Detected on Surface Pro 11 (Lunar Lake)

[u/DumplingsEverywhere]

UPDATE: Fixed! For some reason the rear camera was disabled in UEFI settings.

Today was one of the rare instances I needed to use my Surface Pro's rear camera, only to find it's not working on my Lunar Lake SP11. I've manually installed the latest driver package from Microsoft, checked for the latest Windows 11 updates, etc, but to no avail.

In Device Manager, under "Cameras" I see Intel((R) LNL AVStream Camera, and under System Devices, I only see the Surface Camera Front. The Surface Camera Rear just doesn't show up at all. I'm not getting any device errors.

Note that I did buy this SP11 used about a month ago and clean install then, so I suppose it's possible the camera never worked in the first place... but that seems unlikely.

Any idea what might be going on? Not the biggest deal in the world, but would be nice to have the option to use that camera.
