From various list of works that I could find, Wikipedia, thriftbooks, archive.org, and Pioneer Library (the most complete list), there doesn't appear to be an exposition for 2 Peter.
He did write expositions for the Gospel of John, Philippians, and Hebrews as well as books on Abraham, Jacob, Joseph, Moses, Samuel, David, Elijah, Jeremiah, John the Baptist, Paul, and Peter.
You may find references to 2 Peter from his non-Exposition works:
