Right, you can't override this.
HOWEVER: these cut lines, and also the Common Edges btw, are ALWAYS in lineweight 2... So you'll need to adjust the assigned lineweights off all system families in the Object Style to match this, and then assign the thickness you want to Lineweight 2.
I'm guessing that in your case you set the Walls to have a Lineweight 1 (which is by the way also reserved for the hatch patterns)
