所以我的问题是，我们可以在智能合约代码部署后添加更改（功能）吗？

No, the very foundation of a blockchain is its immutability, meaning that once a set of data is sent to the blockchain, it can never be modified or changed in any way. Therefore, once you push a smart contract to the Ethereum blockchain, it cannot be changed or manipulated in any way.
It's not entirely possible due to the fact that an ERC20 token is embedded into Ethereum's blockchain. So, when miners are mining the Ethereum blockchain, they're essentially mining every ERC20 token as well.
