Easy fix, put a piece of black tape over your camera and take it off only when you want to use it. I'm so smart I even surprise myself.
It's not even that complicated. They can't see anything anyway because my surface sits with the keyboard closed (backwards) which blocks the backside camera underneath my monitor stand so the only thing they'd see from my front camer if they cared to would be the bottom of my monitor stand.
I use the camera so seldom (occassionally in a Zoom meeting) that I don't worry about it too much. I have a docking station that I connect a single plug into the Surface and It handles all my other connections...network, monitor, speakers, external drive, backup drive, etc. I have the exact same set up at home when I work from there. One plug and everything is the same - keyboard, monitor, mouse, speakers, etc.
Even if they got me while I had the camera facing me, they would only see the same sad photo that you see (my avatar). That was actually a capture from a Zoom meeting.
However, it should be noted that while I wear a shirt and a sweater vest quite a bit, I do not wear pants very often in the office. This keeps my co-workers at the cool wary distance that I prefer so that they don't coming running over to ask me questions every five minutes.

I also occasionally take my dentures out and set them on my desk, just to add some additional level of concern for them.
Basically, they should have just left me continue to work from home but some people have to learn the hard way I guess.
Just me and my polo shirt, my boxers and my compression stockings sitting here typing away!! Now that ought to scare the hell out of anybody who wants to access my camera.
