From the provided information, I understand that you are not able to retrieve the metrics.average_impression_frequency_per_user from the Google Ads API. Kindly note that metrics.average_impression_frequency_per_user is not compatible with the ad_group_ad resource.
In order to assist further, kindly provide us the uncropped UI screenshot of the Google Ads account and also highlight the metrics with segmentation that you require to retrieve via the API.
