Missing amdgpu firmware for AMD Renoir APU's

I really appreciate your help, but I just want to make sure I’m not bricking my system here.

So, first step is to move those ‘renoir’ files I got from the amdgpu directory in the linux-firmware-20210208 archive to the /lib/firmware/amdgpu directory in dom0?

Second step is to run sudo dnf install kernel-latest in dom0?

Third step is to reboot the machine? Or first run dracut --regenerate-all in dom0?

To give you some context I don’t know what initramfs is…
