How can I cause a failover on an Aurora Serverless v1 DB Cluster with no instances?

Question

**End goal**: I'm trying to demonstrate the ability of an application to continue operations after a database failover without manual intervention.

**Specs**:
* Db family: aurora-mysql5.7
* Db engine ver: 2.11.1

**Some Attempts**:
* aws rds failover-db-cluster. This results in "You cannot failover DB Cluster with Aurora Serverless" 
* aws rds stop-db-cluster. States it's "not supported for these configurations"
* modifying the cluster capacity to 0. Only allows for values between 1 - 256

My understanding is I can't use a cluster failover command as with Aurora Serverless the process is automatic. Are there any changes I could make which could guarantee a failover would occur under normal circumstances?

When you have 2 instances in an aurora cluster, you can restart the writer and this will automatically promote the reader to a writer and the old writer becomes a reader.

That would be your failover demonstration.
