Disabling OCI Monitoring for Siebel CRM
You can disable OCI monitoring that was enabled earlier through the
            enable_oci_monitoring parameter. Setting the value of
            enable_oci_monitoring to false prevents Prometheus
        from sending metrics to the OCI monitoring service. 
To disable OCI monitoring for Siebel, include the enable_oci_monitoring
            parameter in the Siebel CRM deployment payload as follows:
{ 
      "observability": { 
            "enable_oci_monitoring": false
      } 
}
For more details on the payload elements, see the "observability" parameters in Parameters in Payload Content.
Note:  Disabling OCI monitoring will not delete the OCI Application
            Performance Management (APM) dashboard that was created when OCI monitoring was
            enabled.
