The auto-focus worked well, but there's no zoom function, and how can I turn off Webcam auto focus of PW310O/PW310P

Please follow the SOP in the Camera built-in Windows 10 from the below link:
PW310O TurnOff AF SOP.pdf

Once you turn off the autofocus, you can adjust the focal point in the Camera built-in Windows 10, then you can preserve this setting on other 3rd party software (e.g., Teams, Skype...etc)

Also, you can zoom in our zoom out in our CamEngine in Windows and macOS:




You can also turn off the autofocus in OBS Studio
