Maximum boot disk size for ZFS

because ZFS in ZFS RAID setup needs BIOS booting (can't do EFI), can the disks which PM are booted be bigger than 2TB?

For examle install ZFS on two 3TB disks in RAID 10?

ZFS uses GPT so there is no 2TB limit.
Previously there were problems booting from larger ZFS-mirrors
What do you mean with larger?
AFIK only if you have may disks you get problems. But this is not a size problem.
