Lenovo Ideapad 3 Gaming - Brightness fixed at full on boot

I’m running Manjaro KDE on Lenovo Ideapad Gaming 3 15ARH7. It’s a full disk install with encryption and hibernate and booting with grub.
When ever I start up the laptop it’s brightness is always fixed to 100% and doesn’t when when I use the slider on the application tray (KDE Plasma). When I reboot the system, it works perfectly fine but I don’t want to have to turn on and reboot every time I want to use it.

The laptop has two GPUs, amd intergrated graphics and NVIDIA 3050 mobile
