Pixel 3a on Android 11 now forcing phone onto XFINITY hotspots and unsecured xfinitywifi hotspots

I noticed when driving that my Pixel 3a (now on Android 11, and completely stock) is now automatically connecting to "XFINITY" hotspots (which I do not want) and unsecured "xfinitywifi" hotspots (which I definitely do not want!) while I'm in public, and I can't stop this unless I completely turn off wifi.

I do not have either of these saved as wifi networks, I cannot "forget" the networks, and there are no options to disable this.

The support page does not have any appropriate information for this.
