If I have received executable file that runs Flask app server locally, can I somehow set Debug mode On? I know it is Flask app and I see in CMD

 * Serving Flask app '09WEB'
 * Debug mode: off
WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
 * Running on ...

Can I somehow change Debug mode: on for executable (not py script)?
