The netio.sys BSOD's still happened after the I made the above post.
I finally worked out what this was; the first thing I looked at, but dismissed. As far as Windows was concerned there was nothing wrong and the app causing the problem (MSI LiveUpdate 6) was an IPv6 bug. Downloaded an updated version from MajorGeeks and the BSOD's have not been seen since. Some other apps still don't work properly, but Windows still doesn't report any problems. If you download stuff using Edge, you may get danger warnings/popups in red letters. This practice stops you maintaining your computer, as sources are outside the Microsoft Store. There's a Brian video (posted elsewhere) about W11 deleting stuff that it considers viruses and other nasties.
