Freshness would work only if you're using a CS version that honors content freshness (http://ndnsim.net/cs.html#content-stores-respecting-freshness-field-of-contentobjects)

If you want completely disable caching (not per specific packet), then you can set
ndnHelper.SetContentStore ("ns3::ndn::cs::Lru", "MaxSize", "1");

1 is the minimum value that you can set currently.  Would it be sufficient?  If not, it is possible to implement a non-caching "content store".  Let me know.
