How do I stop frame time spikes in Far Cry 6 on YMTC TiPlus7100?

Firefights in Yara were a mess with frame times jumping from 12-28ms. I tried disabling the disk in Device Manager, but that broke my streaming setup. I used GamePP Peripheral Driver Conflict Detection to set the sync service to manual. RivaTuner now shows stable 8-11ms frame times, and AIDA64 confirms disk temps at 42-50℃.
