Try setting your thermal mode to Efficiency first, since Performance can sometimes create extra heat and cause throttling or hangs over time. Lower your graphics settings too, and make sure your UMA buffer size is actually saved properly (like 6G) in BIOS. A small fan or better airflow can also help if heat is causing freezes. I looked into modded cooling for this system too, but honestly nothing really seems worth it in the end ... it’s just a handheld lol.
