Android turn off default notification sound and vibrate

Question

I want to post my notification with priority hight and no sound or vibration is needed. I don't even call setSound() or setVibrate(), however, I will always get the default sound and vibrate with my notification. Any advice?

notificationBuilder = NotificationCompat.Builder(context, NotificationKeys.CHANNEL_NEW_ORDER_ID)
            .setContentIntent(pendingIntent)
            .setContentTitle(context.getString(R.string.app_name))
            .setCustomContentView(collapseView)
            .setStyle(NotificationCompat.DecoratedCustomViewStyle())
            .setSmallIcon(R.drawable.ic_app_logo_primary)
            .setFullScreenIntent(pendingIntent, true)
            .setOnlyAlertOnce(true)
            .setOngoing(true)
            .setAutoCancel(true)
            // I also tried with null but didn't work
            .setSound(null)
            .setVibrate(null)

NotificationManagerCompat.from(context).notify(myNotificationKey, notificationBuilder.build())
