I got curious and tried it myself.  References are the emacs manpage in
my system and this message in the mailing list
(https://lists.gnu.org/archive/html/emacs-orgmode/2022-12/msg00520.html).

$ cd $(mktemp -d)
$ git clone git://git.savannah.gnu.org/emacs/org-mode.git
$ make -C org-mode
$ emacs -Q -L org-mode/lisp -l org --batch --eval "(call-interactively 
#'org-version)"
Org mode version 9.6 (release_9.6-126-gf731d4 @ 
/tmp/tmp.1wPdM68xpD/org-mode/lisp/)

At the last step, if you remove everything after --batch, you will have
a clean-slate Emacs with nothing but org loaded.
