Yes though not in any particular user friendly way The only way you can do it currently is by using the HttpAuthenticator subsystem (https://jena.apache.org/documentation/query/http-auth.html) and passing an instance of a custom authenticator that you wrote yourself to the QueryExecutionFactory.sparqlService() call
The custom authenticator could take the AbstractHttpClient instance it receives and add a request interceptor that would add in the necessary headers to the outgoing requests though would need to be careful not to register itself multiple times since client instances can be reused.
