Path in the GPO console
Computer Configuration\Administrative Templates\Windows Components\Microsoft Defender Application Guard Description
The policy allows you to determine whether applications inside Microsoft Defender Application Guard can access the device’s camera and microphone when these settings are enabled on the user’s device. If you enable this policy, applications inside Microsoft Defender Application Guard will be able to access the camera and microphone on the user’s device. If you disable or don't configure this policy, applications inside Microsoft Defender Application Guard will be unable to access the camera and microphone on the user’s device. Important: If you turn on this policy, a compromised container could bypass camera and microphone permissions and access the camera and microphone without the user’s knowledge. To prevent unauthorized access, we recommend that camera and microphone privacy settings be turned off on the user’s device when they are not needed.
