Cannot enable TDX with Xeon 8468

[Jianliang]

Hi

I'm using the Xeon 8468 to try enabling the TDX support to test tdx-tools. NVIDIA demo gives me a sight of Xeon 8480C which supports TDX while 8648 cannot.

Here is a comparison between them: Intel® Product Specification Comparison

They are same in "Security & Reliability"

In my BIOS, it shows:

It seems the TDX choice is always grey. How can I enable it? Does it really support TDX?

Thanks
