+| <a name="input_enable_dynamic_labels"></a> [enable\_dynamic\_labels](#input\_enable\_dynamic\_labels) | Experimental! Can be removed / changed without trigger a major release. Enable dynamic EC2 configs based on workflow job labels. When enabled, jobs can request specific configs via the 'gh-ec2-<config type key>:<config type value>' label (e.g., 'gh-ec2-instance-type:t3.large'). When enabled, labels starting with `ghr-` are ignored during webhook label matching. | `bool` | `false` | no |

 | <a name="input_enable_jit_config"></a> [enable\_jit\_config](#input\_enable\_jit\_config) | Overwrite the default behavior for JIT configuration. By default JIT configuration is enabled for ephemeral runners and disabled for non-ephemeral runners. In case of GHES check first if the JIT config API is available. In case you are upgrading from 3.x to 4.x you can set `enable_jit_config` to `false` to avoid a breaking change when having your own AMI. | `bool` | `null` | no |

By default enabled for non ephemeral runners and disabled for ephemeral. Set this variable to overwrite the default behavior. | `bool` | `null` | no |
