You do not need a bootloader! (https://wiki.archlinux.org/index.php/EFISTUB#Using_UEFI_directly_.28efibootmgr.29) Not even gummiboot.A bootloader does make it easier, though. And it's a good fallback
Part of the reason UEFI was devised was to obviate the need for bootloaders. The Linux kernel contains an EFI stub that will allow the kernel to run as if it were any old EFI executable, so you don't need a bootloader to launch it
