I work in an office building that's less than 5 years old. During the pandemic the elevators started returning to the ground floor and opening their doors. I wonder if the system is configured via the control panel in the elevator or if there's some other interface.

More likely just a static parking rule. Usually "peak" modes are dynamic and only in effect when there is a lot of usage i.e. peak in traffic
