Managing User and Event Location Data in Flutter with Mixpanel

Hello I am working on a flutter project right now and has integrated Mixpanel into it. I would like to ask how to manage user locations and event locations. We need to remove the location data for every users and events sent. Currently I called the "setUseIpAddressForGeolocation" method and set the value to true, so the new Events sent has no geolocation in the default properties. The problem is the existing events still has these data and also for the Users, location data is also saved. Is there a way to remove these?
