How to disable video calling in skype?

Question

Skype

For work purposes, it is necessary to disable video communication in Skype, there were theories about connecting at the port level, but I found only the Skype for Business documentation, but somehow I didn’t come up with more options

Answer 1

Purely physically. Turn off the camera, leaving the microphone - the video connection will disappear, the acoustic one will remain.

Answer 2

In windows 10, you can use the policy to block selected applications from accessing the camera, but if the user is Admin on the PC, then all attempts to block him on the PC will be to shit.
