## Control Guardrails On/Off per Request
You can switch off/on any guardrail on the config.yaml by passing
```shell
"metadata": {"guardrails": {"<guardrail_name>": false}}
```
example - we defined `prompt_injection`, `hide_secrets_guard` [on step 1](#1-setup-guardrails-on-litellm-proxy-configyaml)
This will
- switch **off** `prompt_injection` checks running on this request
- switch **on** `hide_secrets_guard` checks on this request
```shell
"metadata": {"guardrails": {"prompt_injection": false, "hide_secrets_guard": true}}
```

## Similarity Checking
LiteLLM supports similarity checking against a pre-generated list of prompt injection attacks, to identify if a request contains an attack.
