Change custom light template attributes

Configuration
1

I created a custom light using a template for rest integration and is going mainly fine, I just want to know if is possible to change the atributes for this template:

- platform: template
  lights:
    dicroica_4_escritorio:
      unique_id: dicroica_4_escritorio
      friendly_name: "Dicroica 4 - Escritório"
      value_template: "{{ states('switch.dicroica_4_escritorio_sw') }}"
      level_template: "{{ states('input_number.brilho_dicroica_4_escritorio') | int }}"
      temperature_template: "{{ states('input_number.temperatura_cor_dicroica_4_escritorio') | int }}"
      turn_off:
        service: switch.turn_off
        target:
          entity_id: switch.dicroica_4_escritorio_sw
      turn_on:
        service: switch.turn_on
        target:
          entity_id: switch.dicroica_4_escritorio_sw
      set_level:
        - service: input_number.set_value
          data:
            value: "{{ brightness | int }}"
          target:
            entity_id: input_number.brilho_dicroica_4_escritorio
        - service: switch.turn_on
          data_template:
            entity_id:
              - switch.dicroica_4_escritorio_sw
      set_temperature:
          - service: input_number.set_value
            data:
              value: "{{ color_temp }}"
              entity_id: input_number.temperatura_cor_dicroica_4_escritorio
          - service: switch.turn_on
            data_template:
              entity_id:
                - switch.dicroica_4_escritorio_sw
      set_color:
        - service: input_number.set_value
          data:
            value: "{{ r }}"
            entity_id: input_number.hue_dicroica_4_escritorio
        - service: input_number.set_value
          data:
            value: "{{ g }}"
            entity_id: input_number.sat_dicroica_4_escritorio

switch:
  - platform: rest
    name: Dicroica 4 - Escritório SW
    resource: 'http://192.168.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    method: put
    body_on: '{ "state": { "power": { "powerState": "on" }, "brightness": {"brightness": {{ states("input_number.brilho_dicroica_4_escritorio") | int }} }, "color-temperature": {"colorTemperature": {{ states("input_number.temperatura_cor_dicroica_4_escritorio") | int }} } } }'
    body_off: '{ "state": { "power": { "powerState": "off" } } }'
    is_on_template: '{{ value_json.powerState }}'
    headers:
      Content-Type: application/json
    verify_ssl: false

My light works with brightness between 0 and 100, color temp between -100 and 100 and rgb colors.

In attribute states I got this:

min_color_temp_kelvin: 2000
max_color_temp_kelvin: 6535
min_mireds: 153
max_mireds: 500
supported_color_modes:
  - color_temp
  - hs
friendly_name: Dicroica 4 - Escritório
supported_features: 0

As you can see is quite different from the expected.
So:
1- Is it possible to change the brightness scale (0 - 100)? If yes, how?
2- Is it possible to change the color mode (to rgb)? If yes, how? If no, how do you manage to use it (My lamp works with RGB and HA currently is giving me HS)?
3- Color Temperature I know is to much but maybe is possible also… So, if yes how?

Sorry for my english, it is not my main language and sometime is a little sketchy.

Thanks!!!
