 | `tls.certManager.certManagerCertificate.issuerName` | string |           | If specified, it will use a pre-existing issuer instead for the required TLS certificates. **NOTE**: this parameter is related to the deprecated gRPC API and will be removed with it in a future release |
 | `tls.certManager.certManagerCertificate.issuerKind` | string |           | Specifies on what kind of issuer is used, can be either ClusterIssuer or Issuer (default).  Requires `tls.certManager.certManagerCertificate.issuerName` to be set.  **NOTE**: this parameter is related to the deprecated gRPC API and will be removed with it in a future release |
-| `featureGates.NodeFeatureAPI`| bool   | true                                    | Enable the [NodeFeature](../usage/custom-resources.md#nodefeature) CRD API for communicating node features. This will automatically disable the gRPC communication. **NOTE**: this parameter is related to the deprecated gRPC API and will be removed with it in a future release    |

+| `featureGates.DisableAutoPrefix`   | bool | false                        | Enable [DisableAutoPrefix](../reference/feature-gates.md#disableautoprefix) feature gate. Disables automatic prefixing of unprefixed labels, annotations and extended resources. |

This will automatically disable the gRPC communication. **DEPRECATED**: will be removed in NFD v0.17, use `featureGates.NodeFeatureAPI` instead.    |
