Dell Optiplex 7020 - NVMe boot support

Hi,
I have a Dell 7020 and would like to boot from a UEFI NVMe drive in the PCI Slot and ask if someone might either kindly make the changes to the Dell BIOS for me or point me at the best place to start.

The Dell BIOS is in O7020A15.exe on this web page https://www.dell.com/support/home/en-uk/…?driverid=68xwg

Thanks in advance
Nick
