Is it possible to create Static BP Class in UE4

I created a widget where I have, like, 10 boarders. And there’s a piece of code where I create this widget on the server, just to get information from it, how many boarders are in it. When I created the dedicate server, the widget stopped being created, which makes sense. Now I need to figure out how to convert my widget class to static class. That is, whether UE4 has the ability to call interfaces from classes without creating a copy of them in the world?

Maybe you have some ideas how to create widget on dedicated server?
