[Software] Boot Screen Flicker

[ash]

Hi, I am running Debian GNU/Linux Bookworm 12.7, running kernel 6.1.0-25-amd64 on a Victus Laptop with an AMD Ryzen 5 7535HS CPU. Is there any way to solve the screen flickering on bootup.
This my current GRUB configuration:

GRUB_DEFAULT=0
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1 loglevel=0"
GRUB_CMDLINE_LINUX=""
GRUB_GFXMODE=1920x1080

Does anyone know any solutions or how to solve this?

Please describe "flicker". Does it happen once? Constantly? Randomly?

It happens only once during boot, just before displaying a message like 'loading initial ramdisk.' After that, there is no flicker. I recorded the boot screen on my phone and noticed a white screen with some messages. I couldn’t read them because the white screen only appears for a split second, and my phone couldn’t clearly capture the text. So now, I think it’s not a screen flicker but some kind of boot message showing on a white background so quickly that it seems like a flicker. I don’t know why this is happening, but I’ve been facing this issue since the first boot.

Also, I’m wondering if there’s any way to completely hide the boot messages and show only the default Plymouth splash screen, like in Ubuntu.

Plymouth can't load before the kernel loads. Different methods of configuring Grub are available. That currently used on your Victus may need a change in order to play nicer with your BIOS. Is there there a BIOS update available for your Victus?

No, the bios is uptodate. Here is the video of my bootscreen:
