mac address – Device Mac Randomization Android 11

Does anyone know if there is a method to disable device mac randomization on a Samsung note 10,

The devices in question also have Android 11 which could be the problem,

This is not MAC Randomisation for WiFi, it is physical device MAC,

Currently this changes after every reboot of the system.

There does not seem to be a single mention of this issue anywhere that I can find but is causing an issue that needs a resolution one way or the other,

This causes a program that is essential to our business to not allow a registration to our services.

Thankyou in advance!

Cheers
