The ultimate solution would be a fixed MT7922 driver, but try as I might, I haven't been able to find one online.

Perhaps it's time to ask an LLM of your choice to make one.

On Windows, driver signing requirements will make that very hard, unless you buy a signing certificate.

I suppose the code signing cert from the eMudhra fuck-up could work if you can prevent Windows from taking in the recovation, but that opens up a whole different can of worms.
