I'm not familiar with Drake specifically, but for vanilla Quake you would go in combat.qc, find T_Damage(), and scroll down and look for pic related.
Replace the highlighted line with something like:
>if !(attacker.flags & FL_MONSTER)
That should stop them from getting mad at eachother, but still allow damage.
If you want no damage you need a check followed by a return at the top of the function. Something like:
>if ((attacker.flags & FL_MONSTER) && (targ.flags & FL_MONSTER))
>return;
