Sorry, it's unclear what you are trying to accomplish here. Are you saying that your current MDM authority in Intune is configured for ConfigMgr (aka SCCM) and you need to get this changed?
If so, there is zero danger here as the functionality to enable ConfigMgr as the MDM authority was removed from the product 2+ years ago so hasn't functioned in that long either.
Are you sure that your MDM authority is set to ConfigMgr though? Keep in mind that for a new Intune subscription, this is not possible and can only the the result of a configuration made to your Intune subscription multiple years ago.
Instead, are you looking to configure Autopilot (https://learn.microsoft.com/en-us/mem/autopilot/windows-autopilot)?
