Not sure how many cloud vendors are running CPU's with AVX-512 support, but I imagine that if they do you either have to pay for exclusive use of a single CPU (all cores), or thath they indeed disable AVX-512 instructions by patching the cpuid flags? Note that the downclocking is only really a problem with AVX-512 and much less so with AVX2 and (AFAIK) not at all with AVX.
