On one wall I have to install insulation, but unfortunately its going

personally haven't found a source for insulation that doesn't have
a vapor barrier - otherwise this would be a moot point, but I'm
wondering if I can just push the insulation into the wall - vapor
barrier and all. It should stay put from friction but I didn't want
to just start stuffing it in there and have it turn out to be a bad
idea.

If I understand you correctly you are working from the cold side so the
vapor barrier should be on the other side. Yes you normally could use just
friction fit. As noted the barrier usually comes off easy or you can slit
it if that is not possible. I would use friction fit to keep the barrier
where it belongs.
