Enroll existing macOS devices to Intune

Hey,

How do you handle/enroll existing business macOS devices, which are not yet managed by Intune or any other MDM? 

I believe if i somehow add them to ABM:

• if reseller adds them i can run enrollment profile, no wipe needed
• i can add them with configurator for iPhone, wipe needed

Is for direct enrollment (without user affinity) device license needed? And user (with Intune license) will then use device. As stated here :https://learn.microsoft.com/en-us/intune/intune-service/fundamentals/licenses#device-only-licenses no direct enrollment is mentioned (manual install profile).

What other options do i have for properly manage macOS devices (not byod but corporate) ?

Thanks,

Tom
