We performed a quick research, but were unable to find any information on our current solid state drives and Replay Protected Memory Block support. It is very possible that only some eMMC* flash devices may currently support this type of hardware partition.
We will look further into your question and update your thread once we find a more solid response for you.
We're happy to inform you that we have been able to confirm with our engineering team that all of our solid state drives support RPMB within the Linux* Kernel.
Here are some relevant articles that cover this topic:

We hope this information helps.
We're following up on your thread since we have not registered a response from you.
We hope we were able to successfully answer your question. If you have any further doubts, please let us know.
I didn't see the follow up until today,
Please note that the links you have provided refer to SW support in the host side,
my question was related to the HW support, i.e. Intel SSD card which implements and supports the RPMB protocol, therefore this doesn't help me much.
Hardware wise there are no Intel® SSDs currently supporting RPMB. This is a feature intended for mobile consumer devices, while our solid state drives are geared towards pc/laptop, workstation, and server applications.
