Connecting Quick Sight standard edition to private RDS

I have provisioned Quick Sight standard edition. My RDS in running in Private VPC. I have read many blogs suggesting to create a new security group, modify VPC network of RDS to include new SG and update VPC in Quick Sight. But all this is possible in Quick Sight Enterprise edition. Is there a way to connect Quick Sight standard edition to private RDS (RDS - not publicly accessible)?
