Dynamic QoS Setup with Nighthawk AX3000 Router

Hello,

I recently purchased a AX3000 netgear/nighthawk router for the purpose of multistreaming, but more importantly gaming. I wanted to be able to control which device gets so and so amount of internet and such, so QoS, but when I go to routerlogin on my web browser, I do not see an option for this. I've watched countless tutorials and always, on their netgear routers, they have an option for this, but I do not. Again, I have an AX3000 nighthawk router. If anyone could help, that would be awesome.
