How to skip certain fields from being stored in a event record? example a password_reset EVENT that sends password in payload?

[5hanth]

DEFINE EVENT reset_password ON reset_password WHEN ($event == "CREATE") THEN {
    LET $user = fn::user_from_email($value.email);
    fn::validate_otp($value.otp, $user);
    UPDATE $user.id SET password = crypto::argon2::generate($value.password);
    UPDATE $value SET password = None, updated_at = time::now(); # is this how one should get rid of password being logged in event record?
};
