Calling a controller method within the Addon settings

So currently i have my settings.yaml for my Addon settings. But now i want also call a Controller method with a click.

In my case the user should enter his FTP details and then click a button to check if the connection can be established with a little feedback.

Is this possible within the settings? Because currently i don't find any informations if this is possible or not.
