Amillennialism does not necessarily mean a wholesale rejection of the notion of biblical prophecy. If anything it is largely a disagreement about what the fulfillment of biblical prophecy will look like.
That aside, of course there are always small movements in every faith, but that isn’t usually super meaningful or helpful when talking about the larger group. I’m sure you can find some Catholics that don’t believe in transubstantiation but nobody is out here painting the church as being Eucharist-neutral.
