Question Disable Auto Start/Auto Stop on 2020 Sierra AT4

Hi Friends - I just purchased a 2020 GMC Sierra AT4. The truck is amazing. But, I can't seem to figure out how to "permanently disable" the auto stop/auto start function. Obviously, I can toggle the switch each time I start the vehicle, but I figured there'd be a place to disable it within the settings/preferences.

Am I missing something? Any input would be appreciated.
