3306029 - How to change the URL subdomain for a CPEA SAP Datasphere tenant?

It's required to adjust the URL subdomain of SAP Datasphere tenant which was provisioned via SAP BTP Cockpit (CPEA)

SAP Datasphere 

For SAP Datasphere CPEA tenants, changing the tenant URL subdomain is currently NOT available.
The hostname can be defined ONLY during provisioning of the CPEA tenant, but NOT afterwards.
In other words, the URL of a CPEA Datasphere tenant can be defined when creating the tenant in BTP cockpit, however it is NOT possible to modify this later.
Additionally, it is NOT possible to adjust the hostname of a tenant during plan upgrade. This should be defined during creation of the service instance.

For SAP Datasphere tenant subscriptions (SAP managed), changing the tenant URL subdomain is possible.
See KBA 3339644 - How to change the URL subdomain for a SAP Datasphere tenant? 

SAP Datasphere should have this as a self-service feature, still to be included in the SAP Datasphere Roadmap.
