Leveraging RDS read replica to scale up reading performance

Hi, I am now setting up the grafana server on AWS and use RDS Aurora as its configuration database. I have 1 cluster with 2 DB instances configured and only the primary instance is be able to be used by grafana, and the read-replica is purely used for HA(Failover).

So I am wondering is there a method that I can use the read replica to scale up the reading performance of grafana? My grafana server will be used by most about 30000 users at a certain time in a day.
