I saw a reference in this forum to "DiagramBorderThickness" but it doesn't seem to be what I need. I wonder if there is an option to style the border around the whole diagram?

Hello A.,
You can use skinparam:
as:
@startuml skinparam Diagram { BorderColor blue BorderThickness 5 } Bob -> Alice : hello @enduml
