Is there a way to edit model loading path of a custom node?

I am following a tutorial with the custom nodes installed but a few of the nodes can't load the model that I have put in the mentioned folders. Is it possible to go inside the node and edit the path? I am catching up with some older tutorials and noticed the similar issues. I wonder if there is a way to edit the custom node or if there is a universal node that can replace the loading part.
