But iPXE is not loaded via SNP but from a block device.

Why do you expect to find any parent supporting SNP?

That's the entire point of the snponly.efi build: to automatically identify and use the network interface from which iPXE itself was loaded (analogous to undionly.kpxe for a BIOS environment).

You probably want to build and use snp.efi instead. That will attach to all existing SNP devices.
