Bitcoin Core currently only support to using RDRAND / RDSEED instruction on x86 architecture when requiring to generate a ultra high quality random numbers. For example, a private key.

ARM later added two new similar instructions as well, RNDR (similar to RDRAND) / RNDRRS (similar to RDSEED).

OpenSSL also had a similar feature request on last year. (Implemented)
https://github.com/openssl/openssl/issues/15627
https://github.com/openssl/openssl/pull/15361
https://github.com/openssl/openssl/blob/master/providers/implementations/rands/seeding/rand_cpu_arm64.c

I hope this feature is also available on Bitcoin Core as Bitcoin Core also can using on ARM machine (E.g. A Mac computer using Apple silicon, Raspberry Pi...).
