By picking that option. As part of the iPhone backup to your Mac you’re telling your Mac to backup your sensitive information.
What does Apple call sensitive information?
Your iPhone stored passwords. Any health data collected by apps on your phone.
Your Mac won’t backup sensitive information without that option selected.
Then you’ll get an encrypted iOS backup.
