Can you hardwire an Orbi Sattelite?

I see posts that have mentioned that Netgear is considering allowing users to hardwire sattelite units.  Is this feature available yet?  I have a 3-story house and even with my current setup of Nighthawk AC3200 hardwired to an access point (Netgear Extender AC1200) on the second floor I have difficulty getting a signal on the 3rd floor. I'm hoping an Orbi unit could be hardwired on 2nd floor to the one on the first floor and then meshed to a 3rd unit on the 3rd floor.
