Hi,
Thank you for sharing your feature request.
We apologize for the inconvenience. Unfortunately, the functionality you described is not currently achievable with SP Page Builder. At this time, there is no option to conditionally show or hide sections, rows, columns, or other elements based on the value of a Dynamic Collection field.
We appreciate you taking the time to share your suggestion, and we truly value your feedback. Your request will be considered for future improvements.
Thank you for your understanding.
Best regards
