Customer Supplied Third party non Xfinity supplied Modem inquiry (how to confirm modem not still registered to an account prior to use)

Hello,

Interested in using an approved Xfinity 3rd-party modem (ARRIS T25, non Xfinity-supplied modem).  How / where can the MAC address be checked / confirmed not still registered to an account prior to using?

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.
