Thank you for posting on the Intel ® communities.
I was checking with our "Search product by feature" which allows you to check if a processor supports a feature/technology or not and find a list of the processors that do; however, I was unable to find any processor that matches the combination of Intel ® Optane DC support and Intel ® SGX support.
Please refer to the link below:
You can use that tool to look for other processor that may work for your project and you can select what combination of technologies/features you desire for the product; nevertheless, the one you mentioned shows no results.
