Path in the GPO console
Computer Configuration\Administrative Templates\Windows Components\Microsoft Defender Antivirus\Security Intelligence Updates Description
This policy setting allows you to configure the antimalware service to receive notifications to disable individual security intelligence in response to reports it sends to Microsoft MAPS. Microsoft MAPS uses these notifications to disable security intelligence that are causing false positive reports. You must have configured your computer to join Microsoft MAPS for this functionality to work. If you enable this setting or do not configure, the antimalware service will receive notifications to disable security intelligence. If you disable this setting, the antimalware service will not receive notifications to disable security intelligence.
