--optimize not recognized

[f0x0ff]

Hello, --optimize argument for rebuilding the initrd is not recognized. Same as --full-iso. Looks like exrmod module is not loaded.
On some part of the code it's referred as exr, on another exrmod.

"--optimize" option is not available for external (customer) usage as it would require image signature to allow TAM verification
