Database fields to determine if client is Unmanaged

We have used Unmanaged detector to find unmanaged clients in our environment. Unfortunately, this only give a subset of unmanaged clients.

I would like to run a report on unmanaged clients on the SEPM database itself. Can you tell me what table, field, etc I can find out whether client is unmanaged. Is this a boolean field, or a text field.

Please point me in the right direction.
