You don't say what operating system or filesystem you're using, but on
Linux there is no standard way to change the atimes of a file, so
there is nothing rsync can do about it.

If you persuade your friendly neighbourhood kernel hacker / vendor to
add an operation to do this then I suppose rsync could support it.
