Note

Please note that this will enable only the option in settings in case it is hidden. It will not make VoLTE/VoWiFi work, if the phone does not support it.

Asus can´t enable the option if the carrier doesn´t verify/grant Asus permission to do so. Testing this is a very tedious process.

If VoLTE/VoWiFi is not working for you after toggling it on in settings, this means there´s no config file for your carrier yet.

In my case, VoLTE was already supported by default. I could enable VoWiFi with the third prop because asus already has the correct config in the modem. Lucky for me it works and it was only a matter of making the option visible.
It might be enabled by default in the future if the carrier agrees.
