How to prevent MariaDB from restarting service on Windows after I've manually stopped it?

I am doing resiliency tests for processes that easily take long enough that the user will just walk away and come back minutes if not hours later. I need to emulate something in my system failing so I can ensure my software will wait a few seconds and make a limited number of attempts to reconnect and finish this long-running task. What is not fine is when I manually stop the MariaDB service in Windows it is restarted! I didn't even know it at first except my log viewer was showing database activity, so I pressed F5 and yup, it was started again. Now, yes, I know service recovery is important in most scenarios, but now it's hurting my productivity. I presume there is a setting for the my.ini configuration file though I haven't been able to track down any relevant documentation. There also appears to be no non-default settings in the service properties. How do I prevent MariaDB from restarting the service after I've manually stopped it on Windows?
