The Plundervolt attack made Intel recommend vendors to enable the "Overclocking Lock" flag in the bios (which, despite the name, at least on normal locked cpus just allowed for voltage control). It [https://old.reddit.com/r/XMG_gg/comments/h0wuoh/cpu_undervolting_in_bios_setup_for_xmg_and/ wasn't] a ''hard'' requirement.. but this was just the path of least resistance for most.
