Disable-PnpDevice while device is used?

I have a webcam which i want to deactive via powershell script. I have the following line:

Get-PnpDevice -FriendlyName 'USB-Videogerät' -Class Camera | Disable-PnpDevice -Confirm:$false

But it only works when no program uses the webcam. Is it even possible to deactive a device even though its used by discord or another program?
