A BIOS boot partition is only needed when combining a GPT partition layout with GRUB2 in BIOS/Legacy mode. It is not required when booting in EFI/UEFI mode, and also not required when using a MBR table. It is a very small (1 to 2 MB) partition in which boot loaders like GRUB2 can put additional data that doesn't fit in the allocated storage. It will not be used in this guide.
