Question about AX4200 CBK752 can base by directly connected to satellite.

I was considering getting the AX4200 CBK752. I had a question about if I could link the two devices (base and satellite) together via cat5 so that I would have a more reliable connection between the devices. I want the base to cover upstairs and the satellite to cover downstairs but I doubt seriosuly it will reach reliably without a physical connection. I currently have google wifi and they can do this but I really want to cut down on the amount of hardware I have. (modem, google puck, switch) This seems like an all in-one solution and would cut down the amount of power connections and desk space.
