Turn off wpa3

I’m trying to connect my Canon TS6320 printer (built in 2019) to my Xfinity home internet. I cannot connect it to my WiFi because of the WPA3. I was advised by Canon customer support that I need WPA3 turned off and WPA2 turned on in order to connect it to WiFi. 

ANY HELP WITH THIS FROM A LIVE AGENT WOULD BE APPRECIATED, NOT THE XFINITY ASSISTANT!
