You just set up slices (with format utility on one disk, replicate setup with prtvtoc to others if they are identical). Then you use slice numbers as vdevs to zpool command. Note that slices s0 and s2 are reserved, so you have s1 and s3-s7 to play with. (X86 may expose s8 and s9 - also reserved).

Also note that dedup may require some RAM and maybe a separate fast SSD to cache reads and writes, to be efficient. Otherwise it can bog you down below single mb/s of i/o.
