No. El Torito is just a bootable format extension for ISO 9660. It does
not provide partitions.

This is the DOS partition table in the MBR of the ISO-hybrid image. It
is used only when the image is written to a disk, thumbdrive or flash
card. It is not part of El Torito and ignored (by EFI/BIOS firmwares)
when the image is written on optical media.
