(To be clear, sdbGraph2.ttl is a configuration file for an SDB dataset)
Currently this isn't possible, as far as I know. However you may not

If I understand you correctly each sdb configuration corresponds to
one graph. But SDB can hold numerous graphs, and will work much better
that way.
What you want is an endpoint for each graph, I think? To do that I
suggest writing an proxy servlet that will rewrite queries from:
select ... { pattern }
to
select ... { graph <graphN> { pattern } }
