Re: Is it possible to manually (from code) load 'Realtek UEFI UNDI Driver' from firmware?
The uefi spec defined method to request the bds connect something is using https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Protocol/BootManagerPolicy.h
We have been trying to move partners away from hacky solutions and to this method.

I am developing efi application that should work with network.That will only load drivers that are part of the platform firmware. It

driver installs EFI_LOAD_FILE2_PROTOCOL on the handle that carries
EFI_PCI_IO_PROTOCOL too, for exposing the UEFI driver.) See also
... TBH I'm doubtful a UEFI application is supposed to load option ROM
drivers. That's the job of platform BDS. If "fast boot" is selected,
then the system seems to work as intended -- I'm doubtful that running
your application qualifies as "fast boot" either. I'd suggest disabling
fast boot in the first place.
