Gigabyte g292-z42 Lost admin access to MEGARAC GUI

Hi,

I have a Gigabyte g292-z42 server running with MEGARAC GUI and I don’t have my Administrator password.

I have ssh access and physical access to the server (I can access bios settings).

How can I reset my GUI admin password without touching my installed OS (it works perfectly at the moment)

Thanks

Anyone has an idea on this matter?
