    for(cComments Comment : comments)

        if(Comment.cComment.Id == commentId)
        {
            Comment.cComment.IsPublished = !Comment.cComment.IsPublished;
            if(Comment.cComment.IsPublished)
                Comment.PublicPrivateAction = 'Make Private';
            else
                Comment.PublicPrivateAction = 'Make Public';

            update Comment.cComment;
            break;

You can try updating IsPublished of CaseComment with false. This field is accessible to update using API.
