6th generation processors have SAD / TAD instructions enable; however, they are handled by Intel® Software Guard Extensions (Intel® SGX).
More details about them on the link below:

Thank you for your response.
I have one more question,
Does your answer means that SAD/TAD is disabled when SGX is disabled by BIOS?
Even though SGX is disabled, I think DRAM requests need to be properly routed.
Please correct me.

I am really sorry on the delay of the answer, the case got lost from my queue.
You are right. It is possible to enable or disable the option from BIOS of the board. Intel offers the feature but board manufacturers enable or disable the option by default on the BIOS.
On Intel NUCs, it is possible to enable it through Security tab.
