I want to disable the laptop integrated camerand mic, but at the same time be able to use a USB webcam as the default.plus allow me to also use a plugin mic.
I do know there is a way of disabling cam through modprobe, but that seems to disable all cams from what is said. I cannot find anything in system settings that seems to do the job.
I want to be able to plug in or remove the USB cam as I want without activating the laptop cam if the USB option is not available.

I haven’t tested myself, but these are what I found:

$ echo <webcam bus id> | sudo tee /sys/bus/usb/drivers/uvcvideo/unbind

you can get the bus id (roughly) from:

$ v4l2-ctl --list-devices

Alternatively, try chmod 000-ing /dev/video*, whichever corresponds to your webcam.

See section 2.4

You might be able to blacklist the device:

#Disabling the webcam device.
blacklist uvcvideo

That will likewise blacklist any uvcvideo device.
