from a cursory look, FatPkg/EnhancedFatDxe appears to implement the the
ReadEx/WriteEx methods of EFI_FILE_PROTOCOL
(EFI_FILE_PROTOCOL_REVISION2). I think the implementation uses the
DiskIo2 protocol.

And "MdeModulePkg/Universal/Disk/DiskIoDxe" should automatically install
DiskIo2 on top of your BlockIo2.

So, if you can write a simple UEFI application that uses the *Ex()
methods of EFI_FILE_PROTOCOL, that could be a start. (Nothing in edk2
seems to use ReadEx / WriteEx currently.)

Thanks,
Laszlo
