Multiple SSID (WiFi networks) on Technicolor XB6 router??

I don't see a way on the admin tool to create a second SSID (WiFi network).

My current SSID uses both 2.4 & 5GHz channels which is fine for most of my connected devices.

However, I have a video doorbell that only supports 2.4GHz channel, so I need the ability to create an SSID using only the 2.4GHz channel, like "SSID_24GHz_Only"

Is this even possilbe on the Technicolor XB6, or am I going to have to get my own router to do such a thing?
