Pause an Airflow DAG that runs every 10 minutes for 45 min

Question

I have an Airflow DAG that runs for every 10 min. My cron tab expression looks like this */10 1-8,10-23 * * *. This currently pauses the DAG for 1 hours(9th hour UTC). I want to change this to pause the DAG for 45 minutes from 12:30 to 1:15 AM UTC.

Any way I can achieve this using Airflow?. I read about the timetable concept in airflow 2.2, but I am not sure how exactly this can be achieved.

My options are(Not sure which all are possible):

1. Use a cron tab expression that can handle it
2. Create a separate DAG to pause jobs for 45 min(Not sure how we can do this for 45 min. I know how to pause using a python operator. Confused at setting up pause time)

Anybody have done something similar or have any points on how to achieve this? Any pointers is much appreciated!

I am using AWS managed airflow.
