Guest network Bandwidth Limit on Cudy Dual Band WiFi 6 1800Mbps Gigabit Mesh

Hi All,

So before I go down the rabbit hole I need some advise please.

Im looking at getting the Cudy Dual Band WiFi 6 1800Mbps Gigabit Mesh 3 pack. As per the Cudy agent locally OpenWrt can be flashed in it. I would like to set up the guest network to have a separate password but also want to limit the bandwidth to the guest. is this possible with OpenWrt, has anyone done this succefully.

Thank.
