yes, adding this defcustom to org.el

#+begin_src emacs-lisp
  (defcustom org-cycle-silently nil
    "Non-nil means `org-cycle-internal-global' cycles silently.
  
  No messages about changing visibility state of the Org-mode
  buffer will be outputted anymore in that case. This is especially
  useful to avoid having these messages arrive at stdout or stderr
  when calling Org-mode functionality from an external program."
    :group 'org-cycle
    :type 'boolean)
#+end_src

and then changing the four

#+begin_src emacs-lisp
  (unless ga (message "CONTENTS..."))
#+end_src

lines in `org-cycle-internal-global' to something like

#+begin_src emacs-lisp
  (unless (or ga org-cycle-silently)
    (message "CONTENTS..."))
#+end_src

would do the job.
