Changing min/max temperature of lights

I am using some RGBCCT Tuya led controllers connected to CCT LED strips (precise model TZ3210_3lbtuxgp TS0505B). I am running deConZ as an add on for Home Assistant. I would like to achieve two things, if possible:

  • disable the RGB colour mode
  • change the max/min colour temperature, since the LEDS have a much smaller range than configured in the controllers.

How can I do this? IDo I just edit the DDF file in deConz and change e.g. the default value of the Capability/ct max and ct min attribute. Is that correct? Is there a guide somewhere I can read about this?
