Yeah, ideally I'd like secure boot from the flashed media but failing
that I'd at least like to be moving closer to it (boot without having to
enable legacy boot).

I'm absolutely not an expert on UEFI, and it's likely I'm
misinterpreting some of the more subtle points you wrote, but do you
have more information on the NVRAM restriction?  I've found a fair
amount of references to making secure boot and UEFI capable media (USB
and CD) around the web so I'm surprised it's not possible to make a
portable UEFI image.  Wouldn't that make it difficult to install UEFI
bootloaders on blank systems?
