You wont' typically see a setting in your browser, because credential managers are designed to operate at the system level, so that your credentials aren't "stuck" in your browser. This is why you don't see an option in Chrome settings. You can, however, disable Google Password Manager in Chrome settings, as it is a Chrome feature.

macOS: Settings > General > Autofill & Passwords. Turn on 1Password. https://support.1password.com/macos-autofill/
