I can understand that, but I thnk the issue is that you still want to keep a
Windows instance. W requires secure boot. Linux/Grub can handle that, but
if you don't need W, then secure boot=off and removing the efi partition
completely via fdisk/gdisk will probably allow a standard version of LFS
built grub to be installed and control the boot process.

I beg leave to doubt that this machine will ever be able to boot
without secure boot. Certainly, the manufacturer (and others) seem
to go out of their way to mess with the UEFI so that it is hard to
boot linux, and I suspect the legacy bios boot path is poorly
exercised because the machines all whip with W. Soem of the ACPI
and related settings can best be described as "poor, but adequate
for W".
And although I've updated the "bios" by two versions, the updater
comes in an (unsigned!) zip file which W said was "downloaded from
the internet", and it uses a windows executable to do the update.
Anyway, I'm not about to try removing W - the machine was bought
for a purpose, I've already destroyed enough hardware in the past
without breaking some more ;-)
LOL.
I must be lucky. I've never run into a situation that needs a firmware
update. My understanding, and I'm no expert here, is that a lot of
updates add CPU microcode updates. We can do those when we build the
kernel. Maybe W needs the firmware to do it.
I suppose that some updates fix hardware initialization problems and
possibly the kernel asks the firmware what hardware exists.
I will note that what I've read says the UEFI does not have a "bios"
mode, but sets up the boot via secure mode on/off and what is in the efi
partition. I just use the term 'firmware' as generic for the old bios
firmware and the newer uefi firmware.
It is probably too late, but did you see this:
