As titled, how the frickity frick do you turn off the LIVE STREAM audio on the cameras?

I do not want people who have access to the camera to be able to 'live stream', and be able to secretly listen to conversations happening in the same room as the kasa camera. The tp-link manual shows you can disable audio recording, but I can not find any method to turn off the camera's microphone during 'live streaming'.

Surely, there must be a hidden in-app option or physical override to disable the camera's microphone....
