I assume that you mean eliminate grub for efi.

If you eliminate grub, you either have to set up every kernel/boot in
the firmware with efibootmgr (which can a PitA) or you have to use a
boot manager like systemd-bootx64.efi that'll give you a grub-like
boot menu without the entire grub infrastructure. But in both of these
cases, you need to have your kernels on the ESP. And if you're using
apt to install your kernels (nost likely unless you're self-compiling
them), installation'll fail because dpkg uses hardlinks during an
upgrade and there's no hardlink support on fat filesystems.
