Thermostat has toggle on dashboard but cannot be called in automation (Nexia/Trane)

I’m using the Nexia integration to control my thermostat. There is a setting which I can change from the dashboard called “Aux_Heat” and I need to automate it to be either on or off however the toggle is not an entity which I can call from automation. Is it possible to somehow add it?

Was this solved? Similar goal - Would like to control XL850 Up/Down temp via NFC Tag but proper Control Entity doesn’t seem available. (Can control via Device Icon +/- buttons)
