The `allowList` option lets you specify tag names to exclude from this rule. the `allowCustomElements` option (true by default) excludes all custom-elements from this rule.

```json
{
  "rules": {
    "lit-a11y/click-events-have-key-events": [
      "error",
      {
        "allowList": ["foo-button"],
        "allowCustomElements": false
      }
    ]
  }
}
