no need to restart the service, it will take effect immediately:

```shell
$ curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '

    "uri": "/index.html",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "plugins": {
        "basic-auth": {}
    }
}'
```

The `consumer-restriction` plugin has been disabled now. It works for other plugins.
