Possible to trigger validation check on blur and not on modal change about ngx-custom-validators

Please read the document about FormGroup:
https://angular.io/api/forms/FormGroup#example-1

Since Angular 6, you can edit the updateOn value:

const c = new FormGroup({
   one: new FormControl()
}, {updateOn: 'blur'});

Thanks, is there any way to do it in Angular 4?

As this is a new feat, upgrade to v6 is the best option.
