Encrypting SystemDisk in Alibaba ECS

Question

On checking the following documentation for Alibaba Cloud ECS :-

I see that there's an option to enable encryption for the Data Disks using the following option(s) -

Set the parameter DataDisk.n.Encrypted (CreateInstance) or Encrypted (CreateDisk) to true.

However, I don't see a similar option for encrypting the SystemDisk for the ECS instance while creating the instance / or in ModifyDiskAttribute

Is there an option for doing this which is perhaps not documented ?

Missed checking this in the documentation, it's present in the Limits section of the following article:

You can only encrypt data disks, not system disks.

Also, as mentioned "Data in the instance operating system is not encrypted." on the following official Alibaba Cloud blog:
https://www.alibabacloud.com/blog/data-encryption-at-storage-on-alibaba-cloud_594581

And I think reason behind it would be that the Encryption on the system disk will slow down the processing capabilities.
