How to set all custom frequencies

According to our use environment, we need to change the frequency of all channels to custom.
I saw the configuration items about band and frequency before, and tried to modify, and found that it didn’t work. Excuse me, is there a way to set a custom frequency, including uplink and downlink?

I want to do the same too, have you solved it?

I didn’t found a solution by changing the config files. so I reinstall by compile,before make install,I added my custom band file in the go mods.
