What are the other ways of tackling dementors?

In Half Blood Prince, we read

"Harry fully expected to receive low marks on his, because he had disagreed with Snape on the best way to tackle dementors" - Chapter 21, The Unknowable Room.

Also in The Prisoner of Azkaban,

“There are — certain defenses one can use,” said Lupin. - Chapter 10, The Marauder's Map.

The only way that is specified in the books (7+3) for tackling dementors is to cast a Patronus.

Is there any mention (by Mrs. Rowling perhaps), of another way?

Or is there any piece of magic spelled out somewhere in the canon that we can infer, is effective at tackling dementors?
