Directory structure for UEFI boot (sdd4 in your case) depends on whether
it is internal disk or removable storage: EFI/debian/shimx64.efi and
EFI/BOOT/bootx64.efi (the same file content). Particular implementation
may have bugs. I am unsure which way firmware interprets a USB drive
with multiple partitions in your case. If installer created just one
directory then I would try to copy it to another name.
Do you have an option to choose boot from particular .efi file? If so
try bootx64.efi or shimx64.efi directly
Within the bios secure boot is disabled.
... or grubx64.efi in this case.
Please, show the list of files on sdd4
find EFI | sort
If you can boot to some linux on that machine (e.g. a USB drive with
live image) then show output of
efibootmgr -v
