Hi,
1 - Yes, it is possible to use the same SSID to support both Entra ID (formerly Azure AD) and MAB.
2- Direct integration with Google as an IdP is not natively supported in Meraki Access Manager.
You might be able to use a third-party identity broker like Okta, JumpCloud, etc.

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
Please, if this post was useful, leave your kudos and mark it as solved.
