There is no utility released by Intel or Microsoft for setting parameters for Optane.
Its functioning is dictated by the driver and the motherboard.
The
documentation
says:
What is Intel® Optane™ memory and why would I want a system that supports this?
When this new memory media is installed between the processor and
slower SATA-based storage devices (HDD, SSHD, or SATA SSD), the
computer can store commonly used data and programs closer to the
processor. This allows the system to access this information more
quickly, which can improve overall system responsiveness.
This probably means that it will not apply itself to the M.2 SSD, but only
to the HDD, but there is no guarantee that the driver will do so.
Remark: Replacing the 1TB HDD+Optane by one 1TB SSD will give the same performance
enhancement or better.
