Airport AI - Can the Control Tower at the Airport be Designated Hours of Operation?

For instance, the airport I’m correcting has an operating control tower from 0630 to 2330 local. From 2330 to 0630 you’re expected to use CTAF and contact the nearest airport that operates 24/7 for clearance delivery.
Is there a way to code the scenery file so that the tower doesn’t respond between certain hours of the day?
