Private endpoint support for custom network interface (NIC) is now generally available. This feature allows you to define your own string name at the time of creation of the private endpoint NIC deployed. This enhances customizations to your deployments by allowing private endpoint resources to comply with your naming structure. You can leverage this feature to define a private endpoint NIC outside of the existing format of [Private Endpoint Name].nic.GUID.
Regional Availability:
This feature is available in all public and sovereign clouds.
