Asset default freeze is a flag set at creation of a new asset.  
The only time a smart contract may be able to set such flag is when the smart contract creates a new asset from its application account.  
As such, it is set in the appropriate inner transaction ([Smart contract details - Algorand Developer Portal](https://developer.algorand.org/docs/get-details/dapps/smart-contracts/apps/#asset-create)) using the `TxnField. config_asset_default_frozen ` field ([PyTeal Package — PyTeal documentation](https://pyteal.readthedocs.io/en/stable/api.html?highlight=txnfield#pyteal.TxnField.config_asset_default_frozen)).

Remember that assets on Algorand are _not_ smart contracts contrary to Ethereum.  
In most use cases, assets should be created outside of smart contracts and smart contracts only opt in and transfer assets.
