If you would like to disable the surveys from showing in general, including manual targeting surveys, you can do so using this API.
Disabling Surveys
This API completely disables surveys, meaning surveys will not be shown regardless of the code called.
Surveys.enabled = false;
[IBGSurveys setEnabled:NO];
// Enable
Surveys.setState(Feature.State.ENABLED);
// Disable
Surveys.setState(Feature.State.DISABLED);
Surveys.setEnabled(false);
cordova.plugins.surveys.setEnabled(true, success, error);
Surveys.Enabled = false;
