Huawei LTE modem Network Mode switch

I read the huawei_lte_api documentation and figured out that there is a network mode set instruction and i would love to see a switch to enable/disable 4G from home assistant.

A lot of carriers have unlimited data in some time range, or using 3g/4g. In my case, the speed of the 4G network goes down to 32kbps from 9pm to 12am, and I would love to automate the switch to 3g and back with HA.

Thanks in advance
