Scheduling WAN interfaces

Living in a camper right now, and I have a work provided hotspot and a personal 100GB cricket data only plan. Hotspot is connected over wifi and the cricket data is plugged in with usb tether. Both work great, but I’m wondering if there is a way to have it turn off/disconnect my work hotspot at 5PM (and reconnect again at 9AM) so they don’t get after me for using it for personal stuff?

Now sure the hotspot connect via USB or wifi?

Do you want to disconnect the usb tethering or you can turn off the wifi?
