Hi Noureddine,
There is a corresponding MDM feature for iOS 14 devices that allows for the descrambling of the MAC address when the device is connected to an MDM configured Wifi network. Unfortunately this feature did not make it in our last release, however, we hope to have it available in the near future. I am unable to provide a commit date at this time, but if you raise an enhancement request in the IBM RFE community, you will get updates on it right from our leadership teams.
