A lot of patchbays that aren't specifically designed for audio
applications (we're about the only ones who use half-normalling) have
the normalling contacts on the jacks "hard wired" with a metal jumper
that's part of the contact assembly. You really can't change this.
I've tried sawing them apart but that's not very successful.

If the patchbay jacks have wire jumpers soldered or wire-wrapped
between the top and bottom jacks, you can probably rewire them.
Otherwise, you'll need to live with full-normalling or get a different
patchbay.
