It seems that AMD supports SHA256 and Intel does not. I checked that there is no relevant information. I ask questions here just hoping to get a positive reply

There's a Q&A about which CPUs do/don't have SHA-NI. One of the answers, [Are there in x86 any instructions to accelerate SHA (SHA1/2/256/512) encoding?](https://stackoverflow.com/a/54277666) points out that Cascade Lake doesn't have it. (Your CPU is Cascade Lake; Ice Lake Xeon is out now, but still really new: https://www.anandtech.com/show/16594/intel-3rd-gen-xeon-scalable-review) – Peter Cordes Jun 15 '21 at 13:46

According to Wikipedia the list of Intel CPUs supporting the SHA opcodes are (among others) Intel Ice Lake (and later) processors.
The Xeon Silver 4216 is a Cascade Lake architecture processor which is the predecessor of the Ice Lake architecture.
Therefore the Intel Xeon Silver 4216 does not support the SHA opcodes.
