They cannot be disabled with a NM profile, AFAIK. You can do it with mmcli e.g. mmcli -m a --set-allowed-modes="3g|4g" --set-preferred-mode=4g > What about disabling support for null-ciphered connections?

My impression though is that this setting may be strictly configured in the carrier settings in the modem, if carrier settings are being applied. -- Aleksander
