Loading patched ACPI tables

Hello. I need help in knowing what options I can utilise to ensure a patch for the ACPI table done through grub-mkconfig is saved post-reboot. I need this in order to have my speakers working. It consists of an .aml file and a script - I’ve tested this on other distributions and it works fine.

(for reference);

It would be great if I could have any info on this topic. Thank you so much.

Could you try loading this module?

I don’t know much about grub, so it will surely not work. But running ACPI on boot via systemd should be fine right?
