Operations Manual
Disabling Autoinstalling and Autoloading Known Extensions
By default, DuckDB automatically installs and loads known extensions.  
To disable autoinstalling known extensions, run:  
```sql
SET autoinstall_known_extensions = false;
```  
To disable autoloading known extensions, run:  
```sql
SET autoload_known_extensions = false;
```  
To lock this configuration, use the [`lock_configuration` option](#docs:operations_manual:securing_duckdb:overview::locking-configurations):  
```sql
SET lock_configuration = true;
```
