Yes, but you have to create the configuration in XML/JSON and push it to the APIC.
The attached XML configuration creates and ASAv with three interface:
outside = GigabitEthernet0/0
inside = GigabitEthernet0/1
dmz = GigabitEthernet0/2
You can upload this using the APIC GUI by right-clicking on the tenant in the navigation pane, select Post, the upload the XML configuration. I have also attached a screencast showing these steps.
