Is it possible to connect the extender via ethernet directly to the router for a better signal strength?

Hello team your help on this will be greatly appreciated. I have recently purchased the RE450 WiFi range extender model. Signal is very strong in terms of coverage no complaints there. But after 5-6 h

The product page for RE450 states that it is OneMesh compatible, yet I can't find the option in the menus.... I updated to the latest firmware yet, no luck... Can someone help me please?
