FP16 on Intel Performance Hybrid Architecture?

In 12th and 13th Generation Intel Core Processors Datasheet, Intel Performance Hybrid Architecture indicates that FP16 is supported in both processors as long as P-cores are enabled.

However, in x86 FP16 is only supported in AVX-512-FP16 extension which the processor does not support.

So are there any ways to write FP16 intrinsics and code that can run on those processors? Or is there any kind of VEX encoded AVX-FP16 extensions?

As far as I know, the FP16 instructions are supported only for AVX-512 instruction set and there are no plans for VEX encoded FP16 instructions.

So there's no way to use the FP16 feature as there's no AVX512 support and no any AVX alternatives on 12th and 13th Core processors with Intel Performance Hybrid Architecture?
