HarmonyOS 设置横竖屏问题

在ability的onWindowStageCreate方法，windowStage.loadContent里面设置横竖屏，会有切换延迟。还能更早的去设置横竖屏吗

onWindowStageCreate(windowStage: window.WindowStage) {
  windowStage.loadContent(this.jumpUrl, this.storage, (err: BusinessError) => {
    windowStage.getMainWindow((err: BusinessError, data) => {
      // 设置强制竖屏
      data.setPreferredOrientation(window.Orientation.PORTRAIT);
    });
  });
}
