Can I get the data from a class reference?

I need to get component data from Class Reference. And that’s it.
I am using an empty Actor class with one component.
The component has the structure I need, the data of which I want to receive. Not creating an object.
Like in a prefab in Unity.
In Unity, an object may not be created, but you can get all its data from it, and data about each of its components, without creating it.
