Computer Configuration\Administrative Templates\Windows Components\Microsoft Defender Application Guard Description
This policy setting allows you to decide whether auditing events can be collected from Microsoft Defender Application Guard. If you enable this setting, Application Guard inherits auditing policies from your device and logs system events from the Application Guard container to your host. If you disable or don't configure this setting, event logs aren't collected from your Application Guard container.
