Brightness setting does not work when "acpi_backlight=vendor" is set in the grub with NVIDIA drivers v.510.47.03 on ASUS GL502VS laptop

Hello,
the brightness setting does not work when “acpi_backlight=vendor” is set in the grub with NVIDIA drivers v.510.47.03.
The notification of the change of setting appears well on the screen but the brightness remains at full.

With this setting the Fedora system takes a few seconds to start.
If I change the “acpi_backlight=native” Fedora
takes 1m52s to start and the brightness setting works again.
