During the upgrade wizard unable to uncheck the "enable secure bus binaries"
The issue was identified as the hub_secure v9.33 was installed on the primary hub while the environment doesn't have secure probes.
- Deploy the hub v.9.33 to overwrite the hub_secure v9.33 which will cause the primary hub to restart.
- Run the UIM upgrade 20.3.0 setupCAUIMServer.
