How to set up Tenda Nova mesh for wired backhaul - MW5, MW6, etc.

Hello

This is all very helpful. Thank you!
I consider buying the mesh MW6. Is it possible to first connect a switch to the ISP router, and then, through wall sockets, connecting the primary node, secondary nodes, and other devices (such as laptop, printer, TV), and so on? I attach a picture (based on the schemes presented here) to explain.
In that case - does it matter which devices to connect directly to the ISP router, and which to the switch?

Thanks again,
