You must edit the theme code or you must use action/filter hooks provided by your theme to add code and or content to the site.
I don’t know anything about how your theme works and it is unlikely that you’ll get answers here unless someone that has experience with this theme sees your question.
The best source of information on how to make changes to your theme to show fields created using ACF would be the developer you purchased your theme from.
Once you know where and how to make your changes then someone here might be able to help you with ACF related code.
