Hi George,
Currently, there is no built-in option for that in Kadence. There is also no filter we can use to change the layout like that.
We currently have an open feature request that might be similar or related to what you are looking for though: https://www.kadencewp.com/kadence-theme/feature-requests/narrow-plus-left-and-right-sidebar/
If you could please take a moment to comment your use case scenario on the feature request and upvote it, that will help the development team better understand the importance of adding this feature.
Please note that I don’t have a firm timeline on when or if that might be developed/added.
Let us know if we can assist you further.
Kind Regards,
Michael Taro
