Using a WiFi Internet Booster Range Extender EX6410 only as Ethernet port

We have NETGEAR Orbi Tri-band Whole Home Mesh Wi-Fi System (RBK50) and NETGEAR Wireless Mesh WiFi Internet Booster Range Extender | Covers up to 2100 sq ft and 35 Devices with AC1900 (EX6410). We bought the extender to use the ethernet port for Sky Q box which has a tendancy to drop its wifi connection on a regular basis. We don't want to use the wifi signal from the extender as its not as good a signal as we are getting directly from the Orbi system. As is doesn't appear as a seperate network we cannot avoid it. Is it possible to switch of the wireless signal it is emitting?
