Is there a way to easily disable the add button on a collection field if we decide we no longer want it to be a collection field?

CASE SCENARIO:  Form built with a complicated table within a collection field.  After testing, we realize that one line is all we need on the table or the need for more than one line is no longer valid. 

I can't seem to simply pull the table out of the collection field.  Would rather not have to rebuild the table from scratch.  Tried just removing the word ADD but the form configuration would not let me.  

What about hiding just the view of that ADD option?  Could it be done using CSS or JavaScript and, if so, what would be the code to use?
