If your only experience is with the legacy CSM, it might be worth looking up how UEFI systems boot. 

The tl;dr story is that the system firmware has some variables that say where to look for EFI volumes, and it launches EFI executables from those volumes. No tiny boot sectors or second stage loaders, just EFI executables on a FAT32 filesystem.
