It doesn't seem so :/

The compositing manager is really just a piece of software, like the
window manager (in xfwm4, it's embedded)

The compositing extensions in X do'nt know nothing about shadows,
transparency etc. They just give hooks so that one can implement a
compositing manager, but that's all in compositing manager.

In other terms, ther earen't any option in X to configure the
compositing manager because it's really not X that does it.

Like any software, the compositor can be made configurable or not. I
choose to make it not configurable because I prefer to have it like that
(by design it's just my choice to do so).

If you want a highly configurable compisotor, you may want to try
xcompmgr (only available from CVS AFAIK) - That
compositing manager can run sperately from the WM, so you can run it
with any WM including xfwm4 if you disable its internal compositing

xcompmgr has various side effects though, YMMV.

I hope all that makes sense ;)
