4K vs 512byte sector drives on Seagate Constellation E.2

I've a Seagate constellation ES.2 which supports 4K sectors but diskinfo shows it as 512bytes;

da0	512	3000592982016	5860533168	0	0	364801	255	63

I understand that Seagate ships these drives to be compatible with 512byte sectors so that older Windows OSs work on the.

But I'm unsure how to get this drive to report as having 4K sectors.

I'm really asking from a ZFS perspective as my vdevs show with an ashift of 9 via the zdb command.

I'd rather forgo the gnop hack as I prefer a cleaner approach.

Any info or insight would be greatly appreciated.
