Netapp powershell cmdlet Set-NcCifsSecurity does not allow set advertised encryption methods

[rb11]

If I run Get-NcCifsSecurity I can see: "AdvertisedKdcEncryptions : {aes_256, aes_128, rc4, des}" but there's no parameter on Set-NcCifsSecurity with which I can update this to "@['aes_256', 'aes_128']". I'm on NetApp Release 9.17.1P3.

How do I get this added?

Thanks.
