Switch off read/writes to DB from runtime engine engine

I am using Camunda process (workflow) for microservices orchestrations. I want to restrict database read/writes. Is there any configuration to do so?
thanks

If you are using any of the Database as a Service of AWS services, you can configure IOPS(Read/write operations per second). In camunda you can configure processengineconfiguration via Java API or XML based configuration to specify number of threads/ number of open connections in connection pool. You can’t specifically control the read or write operation in camunda.
