Sorry, no. Netgear designed the router models (of both the residential Orbi and Orbi "Pro") to be "only a router". They cannot be attached to another router and function as a satellite. Other manufacturers designed their products where each device can serve in either capacity, but not Netgear.
An Orbi router can be placed into Access Point (AP) mode and wired to an Orbi router and will function as an ordinary access point. i.e. it will not be "integrated" with the primary Orbi. Devices will not "roam" between it and the primary Orbi. If it is set up with the same SSID/password/channel as the primary Orbi, it will interfere with the primary Orbi. In other works, it is like attaching a $50 access point from any brand. Sort of a waste of an expensive device.
Generally, people do not report being happy using a router this way. (I think a lot of these surplus routers wind up on eBay.)
