AiMesh Question

I'm looking to replace my eero gen.1 3-node system with two Asus routers, running AiMesh. I have an older RT-AC68U that was used before the eero and is in great working order. I will most likely purchase the AC86U as the main router/ap.

My question is since I'm using FiOS and require the quantum router (wifi disabled), I would have to place the AC86U in AP mode. Does AiMesh provide for this type of setup, or does it require a main router vs AP.

Thanks!!
