If it's a chippable ECU, then yes.

There's automatic ECUs chipped all the time, however, the OBD1 P72s I've seen are not like the rest of the OBD1 family of ECUs. They're not chippable. You could try using a chipped automatic ECU (P75 converted to VTEC perhaps) with the appropriate conversion harness that has auto wiring as well. I know it's been done before, so there must be something out there about how to do it. Unfortunately I've never seen it first hand, so I don't want to offer any bad advice.

so if i can convert my p75 to vtec, can i tune it with neptune?

NepTune is for OBD1, not OBD2.
