embed signature file for imgverify

[hackyman]

Dear members,

Thank you for your help in advance. I couldn't find a way how to embed the signature of the file (lets say I want to verify image of initramfs) for imgverify . I know I can download it from the https server(assuming I have right certificate embedded to ipxe.efi), but would be nice to have an option to embed it on compile time (I don't care about the size of the final binary).

Best.
