I assume you are talking about the button that comes from the EventLink plugin and adds to the bottom of the details article?? If so, you can manually insert that button wherever you want it. If you manually insert it, it will override the automatically placed button. But you could manually insert it at the top, the bottom, the middle, the sides... This forum category has a sticky post for using the EventLink plugin and gives more instruction for manual usage. There's also a video tutorial for it. Thanks.
