It is not, and a feature request is probably going to go nowhere.
The reason configurability seems like a bad idea is that null sort
direction is wired into things like index contents.
It'd probably have to be done at CREATE DATABASE time, like the setup of
the database encoding is.
Personally I can't say I really see the point. I suspect database
designs that rely on the sort order of NULL anyway - they usually seem
to be trying to use null as a concrete value rather than an "unset/unknown".
Even if that's not the case here, I suspect (OP) that you'd have to
produce a viable patch for this feature if you want it supported, as I
doubt there'll be enough interest for anyone else to want to implement it.
