Hikey 970 NPU Power

Hi all,
I couldn’t find the NPU (Or maybe ICS) on the Soc power interface schematics (https://www.96boards.org/documentation/consumer/hikey/hikey970/hardware-docs/files/hikey970-schematics.pdf).
Could you share more information about the NPU power source?
Thanks!

Maybe the NPU power integrated into A kernel, so we can’t see independently
