how anonymize Google Analytics for iOS for GDPR / RGPD purpose

Question

I wonder if it is possible to use Google Analytics for iOS in a anonymized way.
It is currently possible to :
- disable IDFA (https://developers.google.com/analytics/devguides/collection/ios/v3/optional-features)
- anonymize IP (https://developers.google.com/analytics/devguides/collection/ios/v3/advanced)

But is there any other identifier that Google Analytics may use ?
for exemple, does Google Analytics use the IDFV ? (https://developer.apple.com/documentation/uikit/uidevice/1620059-identifierforvendor)

You can find everything here: https://support.google.com/firebase/answer/9019185?hl=en

Site and/or app owners using Google Analytics and Google Analytics for Firebase (aka “customers”) may find this a useful resource, particularly if they are businesses affected by the European Economic Area’s General Data Protection Regulation (GDPR), or California's California Consumer Privacy Act (CCPA), or other similar regulations.
