DFCI reset verification code - where to find the documentation around this process?

I have a Surface Pro device where I need to re-enable 'boot from USB devices', but I need to follow the 'Enter DFCI reset verification code' process since 'boot from USB devices' is greyed out due to Company policy. None of the admins in my company have ever done this process before.

 

Question: where can I find documentation around DFCI and 'Reset Requests' that describes this process in detail?

    I have the same issue and cannot find an easy solution especially in the scenario where the Surface device won't boot at all due to a hardware fault.   This means I can't boot to Windows to have policy changes or removal from Autopilot apply or remove settings.  

    There is so much information on locking the UEFI settings but not removing in all scenarios.  I understand this may well be to do with security.  

    Just to illustrate I am using this option in UEFI settings to try to generate this "validation phrase"  but who holds the validation phrase?   Is it in Azure /Entra or does it need Microsoft?
