Completely strip out the firmware for AVX-512, and dictate that future BIOS/UEFI releases on all motherboards going forward cannot have this option, lest the motherboard manufacturer face some sort of wrath / decrease in marketing discretionary funds / support. Despite the shift to 5nm, adding features like AVX-512 means the actual chiplet sizes havent changed much. It was working on early silicon, even as far as ES1/ES2 silicon, and was enabled in the firmware. Most consumer-grade processors these days come with support for both AVX and AVX2, with only high-performance processors supporting AVX 512. However, support was only brought to the high-performance Xeon Phi Knights Landing processors back in 2016.
