Can an EFI application automatically load and run before the BDS phase?

Question

Can an EFI application automatically load and run before the BDS phase, immediately after loading all DXE drivers? If I include the application in the .fdf file immediately after the DXE drivers, will it be automatically downloaded and executed?
