I improved my AM5 PC boot times with this one setting change

The launch of AMD's AM5 platform was a confusing one for the press, who had to review chips and motherboards on day one. We were among them and found a few issues too, but the most confusing change was the lengthy time to train memory for DDR5 RAM. This could take a minute or so, sometimes more, which would confuse everyone since nothing would be displayed on-screen other than an LED or system BIOS code for memory. Although the initial boot time takes a while, subsequent boots are notably faster, but there's a quick UEFI change to address this issue altogether.
