I'm experiencing crazy disk read delays when switching maps in Farming Simulator 25 on a Biostar B650MT. How do I fix this lag?

There is nothing more frustrating than being stuck on a loading screen for a full minute when opening a massive farm save; the input lag is just unbearable. Checking the hardware logs, I found that the M.2 slot on the Biostar B650MT was suffering from severe link synchronization failure during random small-file reads, with speeds swinging wildly between 200 MB/s and 3000 MB/s. I wasted a ton of time reinstalling storage drivers in Windows, but that did absolutely nothing—it was a complete shot in the dark. I finally went into the BIOS $\rightarrow$ Advanced $\rightarrow$ PCIe Configuration and forced the link speed to Gen4 instead of 'Auto,' and flashed the latest AGESA firmware. In CrystalDiskMark, my random 4K read performance jumped by 15%, and map load times plummeted from 60 seconds to just 12 seconds. I did run into a snag where the CMOS cleared and messed up my boot order, so I had to manually reset the boot drive. The chipset now stays cool at 42°C - 48°C, and after ten consecutive restarts, the loading is consistently fast.
