I think I figured out how to disable the google sign-in question in chrome without having to sign up with a google/gmail account. I will list those steps below.
The steps to find it:
- Settings
- "Privacy and security"
- Third-Party cookies
- See all site data and permissions
- Filter for google
- expand it
- Find accounts.google.com
- Scroll down to "Third-party sign-in"
- Set to "block"
- test it
