In the second screenshot that you have attached, there is an checkbox called "Initially check all tree objects". It is selected by default. This is the reason why you see all the objects selected when you open the NAR file (third screenshot).  If you deselect the option "Initially check all tree objects", none of the objects would be selected when you open an archive NAR file.
When you open a archive nar file is there a way to mass deselect all luns, enclosures and drives under the lun tab? I can do a cnt a to select all but it wont deselect all check marks.
