For this use case it's a bit more complicated than just deploying the unifi AP.
First of all you would have to disable the radio on the Homehub and disable DHCP.
If you're sticking with a black box solution you would then need something like the USG gateway to manage DHCP and security functions then vlan separate the guest and main wireless networks which means purchasing a managed switch. The unifi bandwidth controls are assigned on a user group basis and you can assign this via user group to vlan/subnet.
