I noticed my new machine does not have /sys/firmware/acpi/tables/BGRT or /sys/firmware/acpi/bgrt so I decided to update the BIOS before looking more into it.
I knew Richard Hughes had been working on firmware updates for many years so I decided to try updating it from Linux. Sadly Asus is still "Evaluating the service" so no automated firmware update for me.
I downloaded the firmware from Asus website and the zip contained a single file named .cap so based on some reading it should be possible to use it, and fwupdate says it can update that firmware:
system-firmware type, {e820d9ce-ff2c-5ce6-8ba1-c0c1c5703f44} version 1046 can be updated to any version above 1045
But when trying it failed with an error "failed: is not valid format", and verbose logging did not help:

failed: is not valid format
After building it from source and adding some debug, it was failing to parse the GUID because the {} which are displayed by fwupdate -l must not be given in the parameter, and it does a lot of work before validating the arguments 🤦
Anyway, after calling it correctly all went fine:
system-firmware type, {e820d9ce-ff2c-5ce6-8ba1-c0c1c5703f44} version 1553 can be updated to any version above 1552
But I still don't have /sys/firmware/acpi/tables/BGRT.
