Is it possible to prevent _ga and _ga_* being set by Google Analytics module prior to consent?

There are some modules for GA. Can you please post the link to the module you are using?

Thanks, Jan, this is the link to the Google Analytics module I am using: https://www.drupal.org/project/google_analytics.

Do you suggest switching into a different GA module that is potentially compliant with Klaro?

As you see on the module page, the module is replaced by Google Tags - thats why we did not write a Service Config for this module.

You can find supported modules in our README:
https://git.drupalcode.org/project/klaro#services-for-google-tag-manager...

Please ask if you need futher support.

Oh, perfect, thank you so much, I am sorry I didn't look enough at the module's documentation file.

I am closing this as the information on the recommended Google Analytics approach is revealed in the README.md module documentation file.
