Android O Limitations for Lower Target SDK

Question

I started testing my application on Nexus 5x with Android O.
My targetSdkVersionis 22.
On the developer's site I read about Background execution limits :
Where:
By default, these restrictions apply only to O-oriented applications. However, users can enable these restrictions for any application on the settings screen, even if the application is not configured to O.

• Where are these settings (to limit Android O restrictions)?
• What is the best practice for these restrictions while I still want to keep below targetSdkVersion?
