Where are the location settings on Asus ZenFone 5?

I can't find the GPS settings on the ZenFone 5 (ZE620KL), on Android 9. I am specifically interested in the location mode, with 3 different values (high accuracy, battery saving, device only). Asus has rolled out Android 9 to ZenFone 5. I don't have a Security & Location entry in the Settings menu. Here is what my Settings menu looks like and once in Security & lock screen: (source: [digitaltrends.com](https://icdn9.digitaltrends.com/image/digitaltrends/asus_zenfone_5z_notch_1-1080x2246.jpg)) I can't find where to choose the location mode. All I have is an ON/OFF switch.
