How do I cancel the - audio making - after every closing of the app?

Hi, I would like to ask this question because I am newbie here and when I started Musescore, it asked me something like: Do you want to export audio every time you close/every tenth saving/only when you want. I chose every tenth saving but now it is exporting it every time I close the app, so I want to get it undone.
Will you help me please? Thanks very much!
