Invalid No VoLTE or VoWifi in MIUI 13

[solemgar]

My carrier doesn't officially support volte or VoWIFI on the Poco F2 pro but until now it was possible to enable it by disabling the carrier check with the usual dialer codes. Since MIUI 13 the same codes don't work anymore, so can't force VoLTE or VoWIFI on the phone. Is there any way to force it back?

Thanks!
