Disable WiFi Calling on Specific WiFi Networks

I use WiFi calling at home as my signal is fairly weak, and it works great. The quality and reliability is great. However, my brother in law's WiFi network isn't as stable and WiFi calling is unreliable there. Also, my car has a 3G hotspot on it with unlimited data, and it also struggles with WiFi calling. Finally, when I'm not home, and especially when I'm driving, I want 911 to see my real address.

So long story short, I want to basically ONLY use WiFi calling on my home network and/or I want to disable it on certain networks. How can I accomplish this. There are numerous articles for Android users that show how this is easily accomplished, but it seems like a shortcoming for iOS.

This is basically unusable now as many WiFi networks especially at airport lounges, hotels, etc. aren't reliable enough for voice calls.

Thanks,
