Ideally, there should be an option to automatically offboard the machines from Defender during the disjoining from Azure AD Process. This works great when your device is still accessible, however what if the device is no longer managed by your organization’s MEM or other configuration management tool? This happens a lot in BYOD scenarios, where once an employee leaves the organization, they just remove the Azure AD Join association without offboarding the device from Defender.

Microsoft Defender for Endpoint (formerly known as Defender ATP) allows you to onboard and offboard devices using various tools such as Microsoft Endpoint Manager, Group Policies or through a custom script.
