Is there a way to uncheck a single choice checked option?

Hello,

This is in reference to my form 'Local Coverage Virginia Order Form'.  In a multiple choice field I see it's possible to uncheck a selection, but I don't see that as possible for a single choice field - once checked, I can't uncheck it if I change my mind.  Is there a setting to change this?  For the moment, I've added a 'None' option or 'No', but this makes my PDF document much longer as I'm hiding unanswered questions to condense and simplify the document version, and this means every question now has to be answered.  Not the end of the world but wondering if there's a setting i'm missing.  I've included a screenshot of the single choice with a none option added versus the field below without the none option that won't change. Thanks!

A Single choice field element is designed in such a way that the other option must be selected to unselect the current choice.

But you can utilize the Multiple choice field and you can limit the entries to 1:

Ah, of course! Thank you!
