Black Screen Laptop

I recently reinstalled popos and the live disk would not load when bios is set to switchable graphics, changing this to discrete option and it works fine.

I went ahead installed but if I switch back to switchable graphics my laptop screen is black, I have an external monitor which works fine but unable to use my laptop screen as it stays pitch black until I change back to discrete option in bios.

I assume its an AMD issue, I have a AMD Ryzen 7 6800 CPU and Nvidia GPU. I had a similar issue in Nobara but the fix is to downgrade the amd firmware then dracut and it works fine. I am not sure if there is a similar option or command in popos that can achieve the same result?

Appreciate any insight, thanks
