Current Assisted Installer documentation for cluster installation mentions that SNO is not supported on IBM Z platform. This is inaccurate as SNO installation is successful via both web UI and API methods.

This comment is mentioned in below 2 places as a note-

Web UI section: Setting the cluster details - Section 4.2 point 12 (https://docs.redhat.com/en/documentation/assisted_installer_for_openshift_container_platform/2026/html/installing_openshift_container_platform_with_the_assisted_installer/installing-with-ui#setting-the-cluster-details_installing-with-ui)

API section: Registering a new cluster - Section 5.5 point 2 (https://docs.redhat.com/en/documentation/assisted_installer_for_openshift_container_platform/2026/html/installing_openshift_container_platform_with_the_assisted_installer/installing-with-api#registering-a-new-cluster_installing-with-api)
