DateTime, open picker with current date, but ngModel should remain empty


I have case wher need to display placeholder for date field “Click to input date”, to let user know what date not filled, ngModel variable has empty string value ‘’.
When picker open it shows 01 JAN 2020 (max date allowed by me), but i need to open picker with today.
If i will prefill ngModel with today date, will be some not correct, it will look like i force user to save it by default.
