Connect to Google Cloud SQL via VPC?

Question

I'm having two Projects in GCP with Cloud SQL & GKE

Project A
  -> Cloud SQL
Project B
  -> GKE Cluster

Now I want to access Cloud SQL from GKE Cluster for which I have two options.

 1. IPv4 address to connect
 2. Clous SQL Proxy as sidecar

But the problem is both of them connects via Public IP. And I'm worried about latency so I was thinking can we access via VPC ? or some kind of internal network ? so the read/write will be more faster.

Cloud SQL now supports private connections: https://cloud.google.com/sql/docs/mysql/private-ip
