If you have a DB cluster running on multiple EC2 instances, you can definitely do that. There are advantages/disadvantages compared to just paying for RDS (eg managing backups, system complexity, and failover) but if you already have that expertise in-house, I can imagine a scale where there might be cost savings.
My comment was specifically discussing the challenges of keeping block storage-dependent, stateful apps within k8s (as opposed to using RDS or rolling your own HA cluster on EC2 or elsewhere). Apologies to GP if I incorrectly assumed they were discussing container volumes more broadly.
