Thanks for reaching out. As per checking, there is still a toggle option for the Fingerprinter sensor. Although this is on the Moto G6 device with the same Android Oreo software. Can you please check if you have these settings on your device? Kindly go to Settings > Security & Location > Under Device Security, tap the Gear icon on the right side part of the Screen > Enable Fingerprint sensor can lock phone. Please check for the screenshot below.
