I don't know about LTE, but I can effectively disable umts in my
huawei modem just by choosing a frequency not available in my country.
Then, when going online the modem is forced to use one of the GSM
ones.

It depends on the modem. See the implementation for huawei in
drivers/huaweimodem/radio-settings.c:huawei_set_band(). It uses the
AT^SYSCFG command that is specific to huawei modems.
