You can change some or all the predefined settings of a Supervisor through the vSphere AutomationREST APIs.
To update only some of the Supervisor settings, use the PATCH https://<vcenter_ip_address_or_fqdn>/api/vcenter/namespace-management/clusters/<cluster_ID>
HTTP request and submit the updated specification in the request body. To reconfigure entirely the Supervisor, use the PUT https://<vcenter_ip_address_or_fqdn>/api/vcenter/namespace-management/clusters/<cluster_ID>
HTTP request and submit a Clusters.SetSpec data structure in the request body. The specification replaces entirely all existing Supervisor settings.
The settings you can configure with the UpdateSpec and SetSpec specifications are the same as the ones that you used for enabling the Supervisor. For example, you can change the storage settings on the Supervisor. Note that the changes that you make to the storage settings after the initial cluster configuration, apply only to the newly created Supervisor control planes.
