@doulos4iesou Hi Greg, that worked perfectly.
Unfortunately, when I open Blender with your userprefs, I can see the noodles, so that is not where the problem lies.

Not that I was expecting that it was a Preferences Setting, but I really have no clue as to what else it could be.
There are no Overlays in the Shader Editor.
And anyway, nobody would ever want to hide the noodles, they are essential, so why would they even make that possible?
Sorry I am not able to help.
