Why don't you invoke Info directly on the manual you want to read (see
the doc string of "C-h i" where it describes what happens if it is
invoked with a prefix arg)?

You could craft up something that modifies the value of
Info-directory-list, but IIRC info.el consults this list only when it
is first invoked.  That is, the contents of the DIR node are computed
only once in an Emacs session.  So changing Info-directory-list after
that will not help at all.
