I assume by your question you have a heat pump. If so, you should see a heat pump balance control under the Nest Sense section of the settings in the Nest app (there's a similar setting if you're using the Home app). Set it to max Savings; this will minimize the use of Aux Heat. The thermostat will start heating earlier when a temp increase is programmed.
