Thank you again for all of your testing. I've made some further changes
to the xorriso options which should bring the image more in line with
standards, following xorriso upstream guidance and I have again boot
tested on {BIOS,UEFI} {cdrom,hd} under KVM. Please give
http://cdimage.ubuntu.com/ubuntu/daily-live/20200915.5/ a whirl and see
if it works any better for you. The changes made are specific to the
UEFI boot options, so BIOS boot testing is not required.

It has always been the intent to get UEFI boot working again on these
systems, it was just non-obvious how to get this working while moving
BIOS boot to GRUB since the previous hybrid mode depended on isolinux-
specific options to xorriso.
The partition table on the current image looks like what we are looking
for and should generally fare better with diverse UEFI implementations.
