Linux (Fedora 35) on a Thinkpad P14s [T14] Gen2 AMD

These are my installation-tricks and notes for running Linux on a 2021 Thinkpad P14s Gen2 with AMD Ryzen 7 5850U. It should also be suitable for the Thinkpad T14 Gen2 AMD as they are technically the same modell.
Meanwhile there is also a good test on youtube and an entry in the arch-wiki, which also comments some points mentioned here.

Automatic Signing of DKMS-Generated Kernel Modules for Secure Boot (Nvidia Driver on CentOS 8 as Example)

First I thank Nvidia for sponsoring the video card.

Secure Boot isn't exactly easy to configure to work with Linux and disabling it isn't really a good idea. Many modern Linux distributions provide the Microsoft-signed shim EFI binary to interpose between Secure Boot and the grub2 bootloader, making booting Linux easy enough if you only ever use kernels and drivers from the official repos. Still, enabling Secure Boot prevents the loading of kernel or modules without a proper digital signature. For example, the propriatary Nvidia GPU driver won't work, unless your distro really went to great lengths to distribute a signed version of the kernel module.

To make Secure Boot play nicely with the driver (i.e. to work at all), we can generate and import a Machine Owner Key (MOK)
