If "NoBD Fix" is homebrew application, than no - as I remember there is no way to sign our own executable/container.
You can only inject original resources like *.rco, *.xml or proper Sony signed *.sprx (and of course eboots), plus disc images for embedded emulators (the only way to get any homebrew apps - but only for PS2, PSX and maybe PSP, with their environment limitations).
