I try to install a system with GPT and grub2 without EFI. AS far as I know I need some space for the grub2 stage2 at the first place of the harddisk with the ID "bios-boot"

But how can I do this via autoyast?

In Leap 15.x and SLES 15, it defaults to GPT layout, even on BIOS-based systems (unless, of course, you use '<disklabel>msdos</disklabel>'). It will automatically create either an 8 MB BIOS boot partition (BIOS) or a 500 MB EFI system partition (UEFI), unless you explicitly define them. My profile only contains a root FS and swap partition, and the installer adds a BIOS boot partition or EFI system partition as needed. I did make an alternate EFI profile which defines a 16 MB ESP, just to save space on VMs, but I have never defined a BIOS boot partition. Note that this does not apply to SLES 12/Leap 42.x and earlier. To run those on UEFI, you need to define an ESP; in BIOS mode, they use msdos layout and no BIOS boot partition.
