Thanks Michael,
I tried to invoke SM3 algorithm in command "openssl req -new -key eckey.pem -x509 -sm3 -nodes -days 365 -out cert.csr", unfortunately got the following error:
140320586413888:error:100C508A:elliptic curve routines:pkey_ec_ctrl:invalid digest type:crypto/ec/ec_pmeth.c:331:

I don't know the detail with the SM3, part, but have you seen:
https://datatracker.ietf.org/doc/html/draft-moskowitz-ecdsa-pki-09
https://github.com/rgmhtt/draft-moskowitz-ecdsa-pki
but, 1.1.1 release notes say it supports SM3. I expect you need to tweak something when "openssl req" is run.
