Ionic 7 PreloadingStrategy

Ionic Framework
1

For Preload all module we could use :
RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules })

But for Ionic 7 where should i define PreloadAllModules?

providers: [
    DatePipe,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy },
    importProvidersFrom(IonicModule.forRoot({})),
    provideRouter(routes),
  ],

IonicModule.forRoot({}) will not accept { preloadingStrategy: PreloadAllModules }
