Does AMD 5950x support Transparent Secure Memory Encryption (TSME) on TUF GAMING X570-PLUS?

I could enable the `TSME` option in bios. But it seems no way to check it whether is enabled actually because it is transparent to the OS.

Hello, @remusclr 

Could you share the details and specs of your build for us to confirm further?
- the current BIOS version, the images of the BIOS main page, and all the manual settings in BIOS
- the brand, model name, and part number of the DRAM currently installed
- the brand and model name of the CPU, GPU, DRAM (part number as well), SSD/HDD, and PSU currently installed
- the OS version and OS build

Thank you.

Hello, @remusclr 

I apologize for the extended waiting time, and currently, we require some additional time for internal verification.
May I inquire about the specific needs or scenarios that necessitate confirming the activation of TSME in the system? 

We appreciate your response in advance.

Hello, @remusclr 

We apologize for the extended wait time. 
After further consultation with the relevant departments, we have confirmed that AMD CPUs require the "pro" specification to support the TSME feature. 
And currently, your Ryzen 9 5950X does not support TSME, so even if it's enabled in the BIOS, the feature won't be supported.
Thank you for your understanding.
