No, you cannot. This is a product support site. The Intel Customer Support Engineers are not allowed to discuss (speculate on) future products, roadmaps or roadmap changes. It you want that level of information, you will need a CNDA with Intel and you will need to go through Intel Marketing to get any information.
As additional information, we would like to encourage you to post the technical information you are looking for in the following community site: https://community.intel.com/t5/Embedded-Server/bd-p/emb-server-hardware-software-firmware.
They can help you with additional questions about Intel Xeon D Embedded Processors.
Also, if you already know the FAE (Field Application Engineer) that corresponds to you, you can contact them to gather more details.
Have a great day.
Intel Server Specialist.
