Lenovo Slim 7 16ARH7 is a machine with switchable graphics between AMD and Nvidia, and the backlight can't be adjusted properly unless acpi_backlight=native is passed. Although nvidia-wmi-backlight is present and loaded, this doesn't work as expected at all. For making it working as default, add the corresponding quirk entry with a DMI matching "LENOVO" "82UX".
