Change GRUB bootloader identity from GRUB to FWS to match kickstart configuration. Add signing of both primary (\EFI\FWS\grubx64.efi) and fallback removable (\EFI\BOOT\BOOTX64.EFI) boot paths, as these are the paths actually loaded by the firmware. Extract GRUB_MODULES to a variable for reuse in both standard and removable installation commands. Add objdump availability check before attempting SBAT verification. Add sbat.csv existence check before reinstalling GRUB.
