Security mode locked in WPA-3, certain devices will not connect.

Recently my wifi updated to automatically manage “some of my settings” to “optimize my network.” However, this means that the security mode is currently locked and greyed out on WPA-3 Personal only, and certain devices, like the Xbox and Ring Cameras, will not connect anymore as they need WPA-2 or a transition mode with both WPA-3 and WPA-2. I was on the phone with support for over an hour and they sent out a new modem and everything, only for the same exact problem to occur. I need someone to unlock the security mode setting or manually change it to a security mode that these devices are able to connect to. Very frustrated.
