Recently I have been doing an experiment to sign smart contracts with bls12-381, but I can't find any tutorial or code for this, Is there any way to do that? please tell me if you know about it.

While EIP-2537 (featuring BLS12-381) has not been approved nor finalized yet, you can run a private network supporting that precompile.
In addition to that, there's a nice GitHub Solidity library (although this library is originally intended to test the Celo proposals, but the code shouldn't differ on Ethereum) that brings some examples of using BLS12-381 operations in Solidity smart contracts (which is a wrapper around EIP-2537).
It does though warn you too that:
These EIPs are not active on mainnet at time of writing, and require specialized client software to execute.
