His response:
We're familiar with this issue, spent a fair amount of time this past year working on a fix, and just solved it a few months ago by compiling a modified bios image with the necessary patch. It resolves the instability (Kmode Exception BSOD) and the 100% CPU usage symptoms observed in Windows 10 following version 20H1, including the most recent 21H2 feature update.
So far we've only been issuing the bios update to existing customers, I haven't really considered selling the patch separately, and it does represent a work product of considerable time investment. EBay no longer allows the sale of non-physical (downloadable) products, but maybe we can bundle it with something from our store
----I've spent enough time on this, will probably purchase this solution
