Can you clarify more what you're trying to do and why you want to do this?
A possibility would be to make the page cache very small, which would make it difficult or impossible for Neo4j to hold any of the raw database contents in memory. Which would sort of accomplish what you're asking, but would really harm database performance.
It isn't something I would recommend doing. Perhaps there's a better way to get where you need to go, if you can provide more details of your use case and need.
