Trying to edit unknown data type

I am trying to edit a property of an “dat package”. To be more detailed, I want to set the lens file inside the LiveLink component using a Editor widget. But I need to change that parameter inside a “Live link controller base object reference”, but I cant do anything with it. I can not cast it, nor can I save it to a parameter.

I have two questions:
What kind of asset is this object reference?
How can I change the properties inside of it?
