There is a patch pending, making 'undolevels' buffer-local. Unfortunately,
Bram hasn't included it yet.

No. There are only two ways handling this. If you don't really change
the buffer, you can disable the undo and later :rundo the
existing undofiles. Or you can work with a copy of the buffer and only
write the changed copy back. The NrrwRgn plugin might be helpful with
this. Both ways are usually not really workable in practice.
