Does Azure Cosmos DB supports RDF schema and SPARQL?

I have a requirement in which i need to design a solution to load data from source to knowledge graph. Also its mentioned that database should support RDF or Graph Database schema and SPARQL engine. SO I am not sure whether to use Cosmos DB graph database for this solution as they mentione d Knowledge graph is the destination. Could anyone please help whether Cosmos DB supports RDF schema and SPARQL as i didn't get any concrete answer for this anywhere?
