Based on the available sources, I don't have information about a way to prevent the default "development" and "production" environments from being auto-created when a new project is created.

The documentation confirms that creating a project auto-creates the default dev and prod environments, but doesn't describe a setting or API parameter to disable this behavior.

Check out these potentially useful sources:
•
Projects & Environments
•
Create a new Environment
•
Modeling and Implementation Components
If you need this capability, I'd suggest reaching out via
Email to confirm whether this is supported or to request it as a feature.
Would you like me to try to answer this generally based on my knowledge instead?
