I have decided to upgrade the primary router in my home network from ASUS RT-AC88U to the new WIFI6e GT-AXE11000. The problem I am running into with the upgrade is the GT-AXE11000 has only 4 wired connections while the RT-AC88U had 8 connections (and there is not an ASUS WIFI6e device with 8). Is it possible to keep my RT-AC88U in the network as a wired switch with the Wi-Fi signals turned off? If so how do I do that?

My AI Mesh network includes an RT-AC86U and an RP-AC1900 that are hardwired backhauls. Can I connect the RT-AC88U to the GT-AXE1100 and then have both AI Mesh devices hardwired to the RT-AC88U? My desired state would be having my PS5, my gaming PC, PS5, xbox series X, and RT-AC88U hardwired to the GT-AXE11000. The RT-AC88U would then handle the two AI Mesh devices, TV, Apple TV, etc

I have mapped out what my network will look like in the floor plan of my house with the desired hardwired device connections listed in Red.
