Depending upon the year of your bike (hint: please add your year and model in your signature) some of the later bikes had a small set screw in the front brake that allowed some minor adjustment but the resting place of it pretty much is what it is.
Aside from bending it (which I don't advise since the alloy might break) I suppose you could loosen the adjustment on it and maybe weld a little something to the spot where it hits the brake switch. However, if you do that and end up having the rear brake too tight then the piston in the master cylinder can get caught on the set screw that retains it and lock up the rear brake - not enough to lock the rear tire but enough so that your brakes get stuck and remain applied and it will heat up your rear rotor darned quickly if you continue to ride on it that way..
