 ## Configuration
 Trivy has a set of builtin rules for secret scanning, which can be extended or modified by a configuration file.
 
-If you don't need secret scanning, you can disable it via the `--security-checks` flag.

-```shell
-$ trivy image --security-checks vuln alpine:3.15
-```
 
 ## Recommendation
 We would recommend specifying `--skip-dirs` for faster secret scanning.

 On the other hand, you should use `disable-rules` if you just want to disable some built-in rules.
 See the [enable-rules][enable-rules] and [disable-rules][disable-rules] sections for the detail.
