Is it caliper brakes? If so, you could try cutting two small slots in the guard under/either side of the brake bolt - then feed a cable tie down one and up the other and tighten it around the brake bolt. Can buy a couple of mill by lifting the guard up. I've done it a few times with success.
Thanks - this might work - I’ve already filed down a nut on the guard so that it recesses inside the fork crown but the guard still slopes down toward the rear of the crown - so will try and rig up something there and lift it a bit.
