Automation to close Linear Nortek zwave garage door?

Is there any way to have the overhead garage door automatically closed if left open after a certain time of night? I’m using a Linear Nortek garage door controller.

That is not possible. You can create a notification for Garage door left open when the door is left open for a set amount of time and/or is left open when a Geo-Device leaves a Geo-Fence.
