There is a builtin `part-first-page' predicate, defined in ly/titling- 
init.ly,
from which you can deduce its converse:

#(define (not-part-first-page layout props arg)
   (if (= (chain-assoc-get 'page:page-number props -1)
          (ly:output-def-lookup layout 'first-page-number))
       empty-stencil
       (interpret-markup layout props arg)))
