FWIW, the 'AVX' CPU feature is part of the x86-64-v3 level of the x86-64 microarchitecture standard [0].
There are chips produced in 2015 that are only supporting x86-64-v2 [0]. Also, according to [1], "The new server-class CPUs released in 2020 [2] do not implement the AVX instruction set."
FWIW2, RedHat Enterprise Linux 9 (RHEL9) requires x86-64-v2 or newer [1]. So, as a reference, they decided to not yet require support for AVX.
