Not able to Encrypt Azure CloudFile. Was able to Encrypt Azure Blob

I am not able to find any class or library to Encrypt/Decrypt Azure CloudFile using C#. I am searching for something which is available for Azure CloudFile.

Following link explain about Blob,but I need similar for CloudFiles.

https://docs.microsoft.com/en-us/azure/storage/blobs/storage-encrypt-decrypt-blobs-key-vault?tabs=dotnet

I need something like below, but for ColudFile.

        BlobEncryptionPolicy policy
           = new BlobEncryptionPolicy(rsa, null);

        BlobRequestOptions options
           = new BlobRequestOptions() { EncryptionPolicy = policy };

Any help guys.
