Disable a built in stat

[4StarGen]

I want to disable the EV adjusted stat, which is built in in pokertracker. Is there a way I can do it? If I delete from the database what will happen? What are my options?
What about make a trigger? Whenever PT4 updates a table, my trigger could set 0 EV for all the hands

Built-in stats cannot be deleted or edited so if you do not want to see your adjusted results you can configure your graph and edit your reports to not display that information.
