It is not possible as of now but we are about to start integrating with DAG managers (Airflow, Dagster, Prefect...). That will give the possibility to schedule the connectors with the proper dependencies.
One option would be that you configure your source/destination with the Airbyte UI or API and with the external scheduler you just reference to a connection object with an id.
We need to run some experimentations and talk to the community to see what makes the most sense. If you have some opinion / scenarios, do you want to write them in the ticket?
