      As a reference, are you pointing the below document in the previous link?


      Intel® Agilex™ Device Security User Guide

      4.4. Canceling Root Keys

      If you are pointing the above then there is no detailed explanation/brief on, How to do that from the FPGA mailbox IP or HPS mailbox IP client? Could you point that document, if possible?

      Thanks
