Removing access control from Basic Mobility and Security for Microsoft 365

Intune_Support_Team So the original post says "There is no need to contact Microsoft Support unless you plan to use System Center Configuration Manager to manage your mobile devices via Microsoft Intune." If I am trying to switch mobile devices from Office 365's MDM (at https://protection.office.com/devicev2 and https://portal.office.com/adminportal/home#/MifoDevices, for example) to Microsoft Endpoint Manager, do I need to contact MS Support? Or is that only if I'm using an actual on-premises installation of SCCM? Thanks.
