Hi Schwenmn,
Thank you for participating in the Apple Support Communities. We understand you'd like to be able to customize the Attention Aware feature. The only option currently is to turn it on or off. This article explains this in more detail: Turn Attention Aware features on or off.
"What are Attention Aware features?
Even if you don’t enroll in Face ID, the TrueDepth camera* intelligently activates to support Attention Aware features. With Attention Aware features, iPhone can check whether you’re paying attention to your device and automatically take action. For example,
- When you’re looking at your device, your display will not dim until you stop looking at your device.
- If you're looking at your device, it will lower the volume sound of your alerts.
If you don’t want to use these features, open the Settings app, tap Face ID & Passcode, then turn off Attention Aware Features."
If you'd like to leave feedback for Apple, we recommend doing so here: Product Feedback - Apple. This is the best way to make your voice heard.
Take care.
