RDS Aurora serverless global database with secrets manager

Hey all,

we would like to deploy a RDS Aurora serverless v2 global database. According to the following documentation there is a limitation in using secrets manager with Aurora global databases: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/rds-secrets-manager.html#rds-secrets-manager-limitations

Is there any best practice to save and share the DB credentials whenever secrets manager is not available?

In addition to this setup we using terraform to track and store our infrastructure.

Best regards
