dropWPBT VS lai

If you want a real solution

This repo claims they can prevent it https://github.com/Jamesits/dropWPBT

There is a method by which OEM's put software into the BIOS itself that Windows then runs the software from. https://github.com/Jamesits/dropWPBT

There's no easy way to get rid of it. https://github.com/Jamesits/dropWPBT is an advanced tool to block it from being loaded, and that link also lists some alternative methods you could try.

The osdev wiki has an article explaining it. Mind you, ACPICA is quite heavy. If you don’t mind running into potential unsupported boards on real hardware (which should be quite rare and the developers will fix it if they can), you might want to look at LAI (https://github.com/managarm/lai). It works fine under QEMU so if you’re only doing virtualization there are no problems. LAI is a lot less convoluted to port, less code and less bloat. In essence, it’s add source files from LAI to your source tree, define and implement a few functions (last I checked less than 10 for basic operations if I recall correctly) and call like two LAI functions to enumerate namespaces and enable ACPI mode. LAI comes with documentation and there is a support channel on both discord and irc, linked in the readme of the repo.
