I usually (using a mallet) gently tap a utility knife blade between the fork crown and lower bearing race. Once you get a bit of space between the two using the slightly tapered blade, a twist will separate the race further. This is usually enough to remove the race, and if not, there will be enough room to insert a flat screw driver or similar tool for the final removal. I find this to be a fairly non-destructive way to go about the process. I have never had to remove a race on a carbon steerer, however.
