Maybe implement somethng like this:


#+BEGIN_SRC emacs-lisp
   (defun n-noexport (x y)
     (let ((tags (nth 5 (org-heading-components))))
       (unless (and tags
 		   (string-match ":noexport:" tags))
 	(org-macro--counter-increment x y))))
#+END_SRC

#+MACRO: n2 (eval (n-noexport "$1" "$2"))


* heading 1

{{{n2()}}}


* heading 2                                                :noexport:notever:

{{{n2()}}}

* heading 3
{{{n2()}}}


HTH,
