The Acer Nitro AN515-58 requires the same quirk entry as AN515-46, since its firmware also advertises the NVIDIA WMI EC backlight GUID. However, on this hybrid graphics setup, the internal display is wired to the Integrated GPU (Intel Iris Xe Graphics). As a result, the nvidia_wmi_ec_backlight driver fails to probe, leaving no backlight device registered and rendering the brightness keys and desktop brightness slider non-functional. Setting acpi_backlight=native allows intel_backlight to register its backlight interface and restoring brightness control. Add a DMI quirk entry so this model uses the native backlight by default.
