On macOS, we can add another JVM while having old versions of the JVM still installed.
How do I point IntelliJ 2017.2 to another version of my JVM?
I can find no such setting in the Preferences
window.
Preferences
> Build, Execution, Deployment
– Nope.
Preferences
> Build, Execution, Deployment
> Compiler
– Nope.

If you don't have a project, you can access the dialog with SDK configuration from the Welcome Screen: Configure
| Project Defaults
| Project Structure
| SDKs.
However, IDE will ask for the SDK anyway when you add a new project, so there is not much sense in defining it beforehand.
