https://wccftech.com/intel-forcing-motherboard-makers-to-disable-avx-512-support-across-all-alder-lake-cpus-through-upcoming-bios/ > During our testing of the Intel Alder Lake Desktop CPUs, we discovered that AVX-512 support was left untouched and could be enabled with ease though this instruction set is all set to be disabled through an upcoming BIOS. > While Intel's Alder Lake CPUs are not officially stated to support AVX-512 instructions, they can be enabled by disabling the efficiency 'Gracemont' cores and leaving the performance 'Golden Cove' cores running.  This delivers slightly better performance and higher efficiency than the standard AVX2 instructions. While the E-cores have their own advantages in a number of workloads, it looks like the AVX-512 instructions net higher efficiency too.
