If you just need a few holes you can drill slowly and use a spray bottle to keep the surface wet so that there is no dust. If you want what your installing to set directly on the clap board and have the shingles come up to it, I would carefully remove the shingles as necessary then get some of the non-asbestos replacement shingles that can be cut to fit.
If you are going to remove shingles wear a respirator, put something down on the ground below the area you will be working, make every effort to remove the shingles in a way that dose not break them, then seal the waste in a plastic bag and check on how to properly dispose of the asbestos in your area.
Good luck.
