API AWS sync connection and ARN

Have someone trying to update ARN information in a Amazon Web Services Asset Sync connection through the API of InsightVM. Not able to find the discovery connection whenever making an API call to /api/3/discovery_connections/ . The account that the client is using utilizes global admin privileges.

Does the API have the ability to get Amazon Web Services Asset Sync connections? And does it have the ability to update the ARN section?

Unfortunately the API doesn’t support these types of connections.
