是否可以动态更改ngbDatepicker格式化程序？

import { Pipe, PipeTransform } from '@angular/core';
import { DatePipe } from '@angular/common';

@Pipe({
  name: 'customDateFormatter'
})
export class CustomDateFormatterPipe implements PipeTransform {
  transform(date: any, format: string = 'shortDate'): string {
    const datePipe = new DatePipe('en-US');
    return datePipe.transform(date, format);
  }
}

<input class="form-control" placeholder="yyyy-mm-dd"
       name="datepicker" ngbDatepicker #dp="ngbDatepicker"
       [ngbDatepickerConfig]="{ dayTemplateData: datePickerConfig }"
       [ngModel]="model" (ngModelChange)="updateDate($event)"
       [readonly]="true" [disabled]="disabled"
       [formControlName]="name"
       [ngClass]="{ 'is-invalid': isInvalid() }"
       [customDateFormatter]="'mediumDate'">

import { Component, OnInit } from '@angular/core';
import { NgbDatepickerI18n } from '@ng-bootstrap/ng-bootstrap';

@Component({
  selector: 'app-date-picker',
  templateUrl: './date-picker.component.html',
  styleUrls: ['./date-picker.component.css']
})
export class DatePickerComponent implements OnInit {
  // ...

  constructor(private _i18n: NgbDatepickerI18n) { }

  ngOnInit() {
    this._i18n.i18nLabels = {
      // ... default labels
    };
    this._i18n.i18nMonths = {
      // ... default months
    };
    this._i18n.i18nDaysOfWeek = {
      // ... default days of week
    };
  }

  // ...
}
