How to change page size while using unified memory

Hi,

I am working on Nvidia DGX system. I saw that P100 GPU can support up to 2MB page size. (https://hothardware.com/reviews/nvidia-pascal-gpu-architecture-preview-inside-the-gp100?page=2). When I used “getconf PAGESIZE”, it shows that the page size is 4096.

Is there a way to manually change the page size in my cuda program?
