Manual Update of Data from Database

I have a multi-page app that takes data that is updated monthly. I manually process the data and export it into a Postgres database (running code on Jupyter Notebooks). I don’t need live update given that it is only updated once a month, it seems like it would be a waste of resources?

The site is running on Heroku, at present the only way to update the data is to restart the dyno. Is there any way to manually refresh how Dash takes data from the Database without restarting the server?
