Not as yet.  I guess you refer to setting priorities?

A new Prolog thread is based on a POSIX thread using default arguments.
The Windows version uses the pthread-win32 emulation to create the thread.

The only thing that touches scheduling is thread_setconcurrency/2 (which
only has effect on a few platforms).

I should not be a problem to add additional options to thread_create/3
and/or encapsulate other POSIX thread scheduling primitives.

Ideally, figure out what is needed and submit a patch.  The file you need is
src/pl-thread.c
