Expected behavior

I was unable to open another topic on the ha forum topic but I have written everything when I wanted to save. You can only write 2 replies which I had done to a previous topic without getting a reply therer. So I could not post it over there .

Another reason to open the discussion forum here for sure where I would be able to ask this question too.

How can i limit the settings for a new schedule on a thermostat to

"automatic" only and the heating option activated ,

I want to hide "ausschalten / turn off" and "heizen- kühlen / heating - cooling" options which I do not need on a radiator.

And when I press automatic I want to have set the temperature option settings on to only have to adjust the temperature.

I know it must have to do with the customize sections but my first attempt here did not work out and I did not find the radiator thermostat only settings or an example for that.

customize:
  climate.thermostat_1_kaminzimmer:
    name: KAMINZIMMER
    icon: thermometer
    actions:
      - service: set_hvac_mode
        name: Set mode
        icon: hass:settings
        variables:
          hvac_mode:
            name: Operation mode
            options:
              - value: heat
                icon: hass:fire

any suggestions.

Actual behavior

shows all options which I can not use cause I can not cool and I can not turn off.
