Unfortunately there is no public api to navigate in the popup content. That's supported by an internal class DatePickerContent, which has a method goToDate(LocalDate, boolean). If you are allowed (and daring enough :) to use internals, you can do so in a onShown handler (to make certain that skin's onShowing listener doesn't interfere):

datePicker.setOnShown(e -> {
    if (datePicker.getValue() == null && datePicker.getSkin() instanceof DatePickerSkin) {
        DatePickerSkin skin = (DatePickerSkin) datePicker.getSkin();
        DatePickerContent popupContent = (DatePickerContent) skin.getPopupContent();
        popupContent.goToDate(LocalDate.now().minusYears(18), true);
    }
});

Note that this requires to open com.sun.javafx.scene.control.DatePickerContent

You can simplify @KirantosTera's code by listening to the pickers showingProperty then clearing the editor using Platform.runLater()

JFXDatePicker jfxDatePicker = new JFXDatePicker();
jfxDatePicker.showingProperty().addListener((observableValue, wasFocused, isNowFocus) -> {
    if (isNowFocus && jfxDatePicker.getValue() == null) {
        jfxDatePicker.setValue(LocalDate.now().minusYears(18));
        Platform.runLater(()->{
            jfxDatePicker.getEditor().clear();
        });
    }
});

Here is my solution, it's not perfect but still good for my issue:

        //Setting datepicker :
        birthday.setDayCellFactory(picker -> new DateCell() {
            @Override
            public void updateItem(LocalDate date, boolean empty) {
                super.updateItem(date, empty);
                //Setting date 18 years ago
                LocalDate today = LocalDate.ofYearDay(LocalDate.now().getYear() - 18, LocalDate.now().getDayOfYear());
                //Disable future date
                setDisable(empty || date.compareTo(today) > 0);
            }
        });
        //Setting actual value
        birthday.setValue(LocalDate.ofYearDay(LocalDate.now().getYear() - 18, LocalDate.now().getDayOfYear()));
        //Cover the value by text
        String pattern = "dd-MM-yyyy";
        formatCalender.format(pattern, birthday);
        birthday.getEditor().setText("Date Of Birth");
        birthday.setPromptText(null);
