That option is only available on Macs running macOS Monterey that meet the requirements. If the option isn't available, see the options below from Erase all content and settings on Mac - Apple Support
If you can't use Erase All Content and Settings
System Preferences includes Erase All Content and Settings only when using macOS Monterey on a Mac with Apple silicon or a Mac with the Apple T2 Security Chip. If this feature isn't available or doesn't work on your Mac, follow these steps instead:
- To restore factory settings, learn what to do before you sell, give away, or trade in your Mac.
- To erase, follow the steps to erase a Mac with Apple silicon or the steps to erase an Intel-based Mac using Disk Utility.
