SDN-RX Spring Reactive programming

I have Neo4j Server with 3.5 version in EC2.
And i have Java Springboot application with SDN-RX dependency. Its working fine in local Neo4j Desktop which is latest 4.x version.
But i found this "The reactive programming model requires a Neo4j 4.0 server on the database side, and reactive Spring on the other." from

My doubt is "Can i connect to Neo4j with 3.5 version from my Reactive Spring boot application ? "
