Precision 7820 BIOS Update ReBar [Help]

Hi,

I am having troubles with the dell SecureBIOS. I was able to use a python script to extract the BIOS from the dell exe and use uefi tool and patcher on it and have a .bin file according to rebarUefi github instructions.

How do I go about flashing this to my 7820? I heard something about shorting a jumper but cannot find any information online. I also would need an external eeprom flasher perhaps? not sure where to go about looking for one.

Any help is appreciated!
