Well that info would hat helped from the start
Search the file Minion.xml, it should contain the settings. Not sure what the exact name is of that setting but I bet it got to do with auto and/or update and is a 0 or false, or 1 or true setting which currently is 1 of true and needs to be changed to 0 or false then.
But why not simply starting Minion once, let it update and change the setting then in the UI? You are always able to see the least 200 addons updated at this website here easily so you always know what updated today! And you'd be able to revert these one time automatic update that way.
