Unfortunately sparql itself is not supported.

If you can transform your queries to cypher queries it should work.

Yes, rewriting your queries in cypher is your best option.
Alternatively there's an "spo" query procedure in n10s but I see that as more suitable to build integrations than to write complex queries. Have a look, it's n10s.rdf.export.spo

A query like this would return all instances of Actor

call n10s.rdf.export.spo(null, "http://www.w3.org/1999/02/22-rdf-syntax-ns#type", "neo4j://graph.schema#Actor")

and would be the equivalent of the sparql query:

select ?s ?p ?o
where {
  ?s ?p ?o 
  filter( ?s = rdf:type && ?o = neo4j:Actor )
}
