Visual Selector options

Is it possible to remove one part of a page not to be checked in the Visual Selector section.
I’ve notice that a part can be highlited in red. Does that mean it will be exclude from the “check for changes” feature?
Thanks for your answer

Yes, @MIA_Distill. The part in the red box is excluded. Is that what you needed?

Note that the text preview in the selector panel shows a preview of this as well.
