Our developers and product managers looked at adding this functionality, but as you can see in the long discussion about it, in the end, the PM's have decided that this is not the best solution:
https://jira.atlassian.com/browse/GHS-6626
At this time, there is not a way to disable the Epic functionality.
Hope this helps!
