I did some ACPI reverse engineering on an old Toshiba laptop some years ago, with the goal of improving the Linux ACPI drivers. Learnt a lot from it, and wrote a blog post that you might find interesting: https://vorpal.se/posts/2022/aug/21/reverse-engineering-acpi... (100% human written, and I hate that I have to specify that these days).
Nice! If it doesn't exist yet, I'd also recommend taking it a step further and writing an OpenRGB controller for it, so even more people can benefit from the reverse engineering effort.
