No sync is necessary from your on-premises domain to your Azure AD domain for CMG. You must of course have a valid Azure subscription to host the CMG resources and an Azure AD tenant linked to this subscription, but as noted, no connection or synch with an on-premises domain is necessary.

@Sochito you should be able to provision CMG as long as the prerequisites are met. There is no dependency on hybrid or Azure AD identity to be in place.  Here is a link to the official docs - https://docs.microsoft.com/en-us/mem/configmgr/core/clients/manage/cmg/setup-cloud-management-gatewa...
