Google Consent Mode V2 is related to Google alone and there is no configuration required within Adobe Analytics. Consent mode integration can be enabled at CMP level, and you can check with both Usercentrics and CookieBot.
We use OneTrust and simply enabled Consent Mode V2 from geolocation rules by turning it ON as in the below screenshot and no additional configuration is required in Adobe Analytics or tag manager end.
However, if you do not use Google Analytics at least as a backup analytics tool, both analytics_storage granted or denied won't be useful to Google. There might still be some gaps in conversion modelling for which you need to consider ads_data_redaction, url passthrough and other parameters as well.
