Expanding a raidz2 VDEV itself is only possible with ZFS 2.3 AFAIU and we do not ship that yet [0]. But if this is for VM storage, you might want to consider a ZFS pool of multiple mirrored VDEVs. [1] has more details. While performance might not be much of an issue anymore with recent NVMEs that provide a ton of IOPS, the additional space usage might still be something to think about in a raidz pool used for VMs (ZVOL).
