Photon 5 ISO images appear to not contain UEFI boot loaders

Describe the bug

Network installing via Kickstart of Photon 5 dde71ec57 (Full, Minimal, or RT) all appear to be missing UEFI boot loaders to boot successfully on UEFI based systems.

root@sm-drp:/mnt# mount | grep photon-5
/srv/isos/photon-5.0-dde71ec57.x86_64.iso on /mnt type iso9660 (ro,relatime,nojoliet,check=s,map=n,blocksize=2048,iocharset=utf8)
root@sm-drp:/mnt# ls EFI/BOOT boot/efi/EFI/BOOT boot/efi
ls: cannot access 'EFI/BOOT': No such file or directory
ls: cannot access 'boot/efi/EFI/BOOT': No such file or directory
boot/efi:
root@sm-drp:/mnt# find . -type f -name "bootx*"
root@sm-drp:/mnt# find . -type f -name "*efi"
root@sm-drp:/mnt#

Unable to successfully boot a Photon 5 system via the network to perform kickstart install.

Reproduction steps

1. download iso: https://packages.vmware.com/photon/5.0/GA/iso/photon-5.0-dde71ec57.x86_64.iso
2. mount iso
3. inspect iso; search for EFI boot loaders
   ...

Expected behavior

For amd64/x86_64 - expect EFI boot loader:
EFI/BOOT/bootx64.efi

For arm64/aarch64 - expect EFI boot loader:
EFI/BOOT/bootaa64.efi

Additional context

Network install from DHCP/PXE server. Environment successfully builds about 50 other Linux distros/versions via Legacy BIOS and UEFI boot (both secure boot, and non-secure boot) currently without issues. Only the Photon Linux ISOs seem to be missing the UEFI boot loaders.

Download and mount the Photon 5 ISO at the reported URL, then inspect the EFI/BOOT and boot/efi paths and search for bootx files as described. Done means the generated x86_64 ISO contains EFI/BOOT/bootx64.efi and supports the reported UEFI network-install workflow.
