Before this patch the sandbox uses 0xffffffea as PXE architecture.

Default boot path: EFI\BOOT\BOOTSBOX.EFI

With this patch it uses the PXE architecture that matches the host. This allows us to use bootmeth EFI on the sandbox to load an EFI binary.

The way things are, this isn't a valid thing to do. It is returning an error to indicate that. The error should be checked. If you use -N then it will do what you want, though.

But what architectures does this work for, with your setup? I haven't been able to get x86_64 to work. I could perhaps try arm64?

Should we document this use of sandbox for your use case, once it is working?
