I don't understand your location, but it seems unlikely you'd pay over $20 for something from Aliexpress. Most countries don't tax small, inexpensive items much. The thermal expansion issue doesn't seem to impact users much unless you notice problems after testing the CPU. Personally, I'm not affected by it and I don't mind the minor boost possible with a slight adjustment. However, I set power limits on my CPUs to stay efficient, so temperature effects aren't a big concern for me.
I also looked for this a while but haven’t found a clear answer yet. It seems you’re asking if it’s feasible to restrict power usage for a non-K CPU on the B760 chipset.
Using i3 12100F on B660 board. I can modify both PL1 and PL2, simply assigning example values.
