Does portworx support Openshift in GCP?

I am installing portworx in OCP running in GCP. Even opened all ports to worker nodes and grant OWNER role to the service account, I am still hitting px-cluster pod errors like "Failed to create drive: googleapi: Error 403: Required ‘compute.disks.create’ permission for … ", or “Failed to create drive: googleapi: Error 403: Required ‘compute.disks.create’ permission for …”

Just wondering if openshift+GCP is a portworx supported platform?

We support OCP on GCP.

On the side note, Portworx is officially certified for Anthos: Partner Archiviazione Anthos Ready  |  Google Cloud

This is to do with the permissions - use the similar settings.
node_config { service_account = google_service_account.px.email
oauth_scopes = [ " https://www.googleapis.com/auth/logging.write ",
