Can I make a single node readonly?

Hi, I have a problem, I want to make a single go.Node to be readonly, which means cannot edit, change color or do anything of it. I just know the property of Diagram isReadOnly: true, But this will make the whole chart readonly. How can I make just one Node to be Readonly?

To disable text editing in a node, set or bind its Part.textEditable property to false.

Or do that on individual TextBlocks by setting or binding TextBlock.editable to false.

What other commands or tools did you want to disable for particular nodes?
