Thank you for contacting Syncfusion support.
Yes, you can remove the merge field label text (text before/After the merge field) when the field value is empty using Merge field event. We have prepared sample to remove the label text by removing the owner paragraph of merge field when the field value is empty. You can download the sample from here and let us know if it helps.
Note: We have used Execute() method in this sample and this event is common to ExecuteGroup(), ExecuteNestedGroup() methods.
