the question and its fittings seem a bit remote to me, since I actually don’t know the plugin and how you can manipulate it (has it its own templates?). However, you can retrieve the value of a field and give it back by the simple the_field(); function. E.g. if you’re inside the loop, having a field named eventlink that links to a post or page could be used as such:
<a href="<?php the_field('eventlink'); ?>">Read more</a>
This would create a link to your post linked to from the backend instead of the plugin’s event page.
This is pretty basic usage of ACF which you can read all over the documentation, so I fear this is not what you actually need?
