How to use Azure Data Factory, Key Vaults and ADF Private Endpoints together

Question

I've created new ADF instance on Azure with Managed Virtual Network integration enabled. I planned to connect to Azure Key Vault to retrieve credentials for my pipeline’s source and sink systems using Key Vault Private Endpoint. I was able to successfully create it using Azure Data Factory Studio. I have also created Azure Key Vault linked service.

However, when I try to configure another Linked Services for source and destination systems the only option available for retrieving credentials from Key Vault is AVK Linked Service. I'm not able to select related Private Endpoint anywhere (please see below screen).

Do I miss something? Are there any additional configuration steps required? Is the scenario I've described possible at all?

Any help will be appreciated!

UPDATE: Screen comparing 2 linked services (one with managed network and private endpoint selected and another one where I'm not able to set this options up):

Managed Virtual Network integration enabled, Make sure check which region you are using unfortunately ADF managed virtual network is not supported for East Asia.

I have tried in my environment even that option is not available

So, I have gathered some information even if you create a private endpoint for Key Vault, this column is always shown as blank .it validates URL format but doesn't do any network operation

As per official document if you want to use new link service, instead of key vault try to create other database services like azure sql, azure synapse service like as below
