{#acc-ics-command-params__table_rrx_lzd_ndc__entry__2}

| Parameter | Description |
|-|-|
| CONNECT_WITHOUT_MID | Specify true to enable MID-less Agent Client Collector installation. If you don't specify a value, the regular MID Server websocket installation is invoked. |
| ACC_CNC | Specify a public gateway endpoint for Agent Client Collector. |
| REGISTRATION_KEY | Active and valid registration key for the agent to communicate with. |
| INSTANCE_URL | ServiceNow instance that the agent is registered with. |
| ACC_ALLOW_LIST | Optional string; to disable the allow list, set ACC_ALLOW_LIST=0. By default, the allow list is enabled. Note: Disabling the allow list compromises your system's security and is intended as a temporary measure while you're updating the allow list. After completing the update, enable the allow list by setting ACC_ALLOW_LIST=1. |
| ACC_VALIDATE_SIG | Optional string; to disable verification of the installer certification validation, set ACC_VALIDATE_SIG=0 that you can add to disable the verification of the installer certification validation. By default, validation is enabled. Note: Disable the certification validation only when using non-standard signature validation tools. |
