Set multiple config parameters

I have a Homeseer HS-WD200+. This dimmer has multiple status LEDs on the switch that can be programmed. For instance, perhaps i want the first LED to blink Red once the washing machine is done. Zwave JS has great documentation on the values for each parameter, Z-Wave JS Config DB Browser. In my case, i would want to set parameter 21 to 1 and parameter 31 with mask 0x01 to 1.

I'm trying to figure out how to do this within node red. I'm thinking, Call service, set_config_parameter, to my entity light.kitchen_lights, however, Im not sure of the proper format to pass each of the above parameters. Any help would be appreciated.
