Not really. I just levered the part off (it was the cable stop for the rear derailleur, which I didn't need as I was going Di2) and sanded off the epoxy left on the frame and polished the paint. You may be lucky - the FD mount on the P5, which was held on by bolts, just fell off once the bolts were removed. No easy way to remove epoxy from a carbon frame, given that the resin holding the carbon fibres together is epoxy as well...
