How to fix 0.5s freezes in Black Myth: Wukong with Fanxiang S790?

I was so hyped for max settings, but entering the forest caused these brutal 0.5s freezes during texture streaming. I tried disabling all background disk scans in Windows, but it didn't stop the NVMe blocking and just made my file search slower. I used GamePP NVMe Queue Depth Configuration to raise the depth to 128 and optimized the write cache strategy. RivaTuner showed frame times converged to 12-17ms, and AIDA64 measured read latency peaks at 140-170ms. HWMonitor confirmed SSD temps at 52-60℃.
