Can I Apply for Multiple Read/Write Splitting Addresses for an RDS MySQL DB Instance?

Sorry, you can't. After read/write splitting is enabled, a read/write splitting address is automatically assigned. You can use the read/write splitting address to connect to the primary DB instance, but to connect to read replicas, you can only use the IP addresses of the read replicas.
