Google Ads API - How to change Engaged-view conversion window

[Daan Jan Grotenhuis]

Hi, I'm using the google ads API to make conversion labels. Im able to set view_through_lookback_window_days and click_through_lookback_window_days, but somehow I can't seems to change "Engaged-view conversion window". This seems to be defaulted to 3 days. Is this a known or is there something I overlooked that allows me to change the Engaged-view conversion window?
