Using BLE along with WiFiStorage from WiFiNINNA without disconnecting BLE?

Official Hardware Nano Family Nano 33 IoT

I've setup a nano 33 to control some LED strips with BLE and created an app to create some patterns. This all works and I can send the patterns to the device over BLE. I now want to store those commands in a file so on bootup I can play the last saved pattern.

I think I've found that you cannot use BLE and WiFiNINNA at the same time? I know theres only one antenna, but I'm not trying to use BLE and Wifi, just the storage aspect of the WIFI. I guess they use the same communication pin so only one can be communicating at once?

 // check for the presence of the shield:
    if (WiFi.status() == WL_NO_SHIELD) {
      Serial.println("WiFi shield not present");
      // don't continue:
      while (true);
    }
    
    // custom services and characteristics can be added as well
    // begin initialization
    if (!BLE.begin())
    {
        Serial.println("starting BLE failed!");

        while (1)
            ;
    }

   Serial.println("1");

    WiFiStorageFile temp = WiFiStorage.open("/fs/testfile");

    Serial.println("2");

This causes it to freeze at the WifiStorage.open line as I only get "1" printed out. If I flip it so I call BLE.begin() first, then my device never starts advertising.

How do I go about reading data from BLE and then storing it in a file? I've read through the thread below and that ends up having to re-advertise after switching. I'm assuming this would cause my app to disconnect from the nano which is not ideal. My app streams the pattern over in many small packets and I wanted to save them to a file as I received them.

After playing around with the example in the thread I linked, it does disconnect the BLE device which will not work for me. Is there a way around this?

void switchToBLE() {
  BLE.begin();
}

void switchToWifi() {
  wiFiDrv.wifiDriverDeinit();
  wiFiDrv.wifiDriverInit();
}

void writeEffectToFile(byte* buffer, int size) {
  switchToWifi();
  WiFiStorageFile file = WiFiStorage.open("/fs/pattern");
  if(file.size() > 0) {
    char buf[] = {'\n'};
    file.write(buf, sizeof buf);
  }
  file.write(buffer, size);
  switchToBLE();
}

void writePropertyToFile(byte* buffer, int size) {
  switchToWifi();
  WiFiStorageFile file = WiFiStorage.open("/fs/pattern");
  file.write(buffer, size);
  switchToBLE();
}

void eraseFile() {
  switchToWifi();
  WiFiStorageFile file = WiFiStorage.open("/fs/pattern");
  if (file) {
    file.erase();
  }
  switchToBLE();
}
