How do I fix storage read latency stuttering in Dota 2 on JGinyue B760M GAMING D5?

Loading Harlan City was painful. Closing processes helped little. I used GamePP NVMe Queue Depth Configuration to increase depth from 512 to 1024. CrystalDiskMark showed read speeds jumping from 3200MB/s to 3500MB/s. HWiNFO64 confirmed drive stability at 45-50℃, ending the stutter.
