This does work as long as you know the file name.  If the Info node
is contained in a larger manual it won't find it this way, e.g.
"info ls" may work if the dir file is up to date, but "info -f ls" won't.

It can actually be done by setting the INFO_MAN_COMMAND variable to "false"
in the environment (this is not documented anywhere and I found this by
checking the source code, but this is not going to change).  Put something
like "export INFO_MAN_COMMAND=false" in .bashrc or equivalent and info
won't show man pages.
