It is not supported. There is no technical issues, though, it won't be supported.

NPIV is a feature to provide multiple path available on one physical port and it has implemented based on the multiport ID (MID) capability on the switch.
So, you have to have the switch with MID capable on the configuration to support NPIV, besides the controller.
