For onboarding through Intune & Microsoft Defender for Cloud, you will need to activate the relevant option. Devices already onboarded will not automatically re-onboard; you will need to create a new policy in Intune, where it is recommended to first assign the policy to a set of test devices to verify connectivity is successful, before expanding the audience. Devices in Defender for Cloud can be re-onboarded using the relevant onboarding script.
