Option to separate EFI and BOOT (XBOOTLDR)

[kforeverisback]

I love the ease of use and the configurability while providing semi-automatic setup.

Currently, I am trying out:

• LVM on LUKS
• Enabling secure-boot (planning to use grub shim)
• Using XBOOTLDR(separate /boot and /efi dir) setup.

I am not aware if such setup is possible with alis.

Could we add an option to separate the EFI and BOOT dir?

Much appreciated and thanks again this awesome contrib!
