Not sure if this is what you mean by tuning, but here it goes.

Access - Geographically Improbable Access Detected - Rule uses the index=gia_summary, which is populated by the Access - Geographically Improbable Access - Summary Gen. You can add a |search to the end of the original search, and add your exclusions there.  Such as | search src!=8.8.8.8  Depends on how wide of an exclusion you need, you may be better off using a lookup table to add exclusions.

Hope this helps.

The Correlation search 'Access - Geographically Improbable Access - Summary Gen' is the one which is actually generated events into 'gia_summary' index.

If you have to whitelist users, ip addresses, locations etc., you can append on this search.
