No... I had not tried yet when you wrote your message.

Now, I have tried, and failed.

I think that a good part of the (my)  problem, is that I have made a custom 
iso, with 
/media/paul/Debian sid h-i386 1/EFI/boot/BOOTX64.EFI
(for info, I used isomaster to add it, after having copied it from my own 
/boot/efi directory (using root access) to my $HOME directory, 
chown $USER ~/BOOTX64.EFI )

My previous DVD show the DVD in UEFI boot mode in the Boot menu of the 
firmware, but trying to boot it return to the firmware.
My edited iso would not even show up in UEFI mode in the firmare Boot menu. But 
"still" works in "Normal" CSM mode.

So I finally realized that CD/DVD are in ISO9660 format... and UEFI partition 
normally need to be in FAT (normally FAT32) to be found by
the firmware.

So... it need to be done once the system is installed... I only have access to 
a working Hurd on UEFI system under QEMU... but I probably could try.
