I know the drivers come in the distro package manager, but, is there a set straight from AMD? Trying to use Brave causes freezes and black screen flashes, which I'm pretty sure is a driver thing.
The AMD drivers come from the kernel. You might try the Debian backport kernel and see if updated drivers help (assuming the kernel parameter isn’t it). It’s currently version 6.6.13.

If this is the same common issue, there's a thread on the forum about it, but IIRC you can add amdgpu.sg_display=0 to your kernel parameters.

If you really want, you could try the AMDGPU Pro drivers, but I'm not sure if they're compatible with integrated graphics if you don't have the expansion GPU.
Grub doesn't actually validate the parameters themselves, but the whole config, so you've pasted it into the wrong spot. It should go in the string that follows GRUB_CMDLINE_LINUX_DEFAULT.
If it still happens, could you post your grub config?
Also some people have had success setting the GPU to game mode in the BIOS too.
