Booting Linux On A Modern AMD Ryzen 6000 Series Laptop / ThinkPad X13 Gen3

Earlier this week Linux security researcher Matthew Garrett shared that Lenovo's newer AMD Rembrandt laptops with Microsoft's Pluton security co-processor would not boot Linux by default. The issue stems from the third-party UEFI certificate not being enabled by default and it turns out is something Microsoft is seemingly now enforcing. Fortunately, I had a Lenovo ThinkPad X13 Gen3 with Ryzen 7 PRO 6850U on the way and so was now able to test this experience under Linux.
