Sure, see the code below. I only destroy and create the ads as done in this guide, but we need to avoid that?

private void RequestBannerAd()
    {
#if UNITY_EDITOR
        string adUnitId = "unused";
#elif UNITY_ANDROID
        string adUnitId = "ca-app-pub-xxxx";
        if (_isDebugBuild)
        {
            adUnitId = "ca-app-pub-3940256099942544/6300978111"; //Fake
            PrintStatus("Using fake banner ad");
        }
#elif (UNITY_5 && UNITY_IOS) || UNITY_IPHONE
        string adUnitId = "ca-app-pub-xxxxx";
#else
        string adUnitId = "unexpected_platform";
#endif

        // Clean up banner before reusing
        if (_bannerView != null)
        {
            _bannerView.Destroy();
        }

        _bannerView = new BannerView(adUnitId, AdSize.GetLandscapeAnchoredAdaptiveBannerAdSizeWithWidth(450), AdPosition.Top);

        _bannerView.OnBannerAdLoaded += () =>
        {
            PrintStatus("Banner ad loaded.");
            OnAdLoadedEvent.Invoke();
        };

        _bannerView.OnBannerAdLoadFailed += (LoadAdError error) =>
        {
            PrintStatus("Banner ad failed to load with error: " + error.GetMessage());
            OnAdFailedToLoadEvent.Invoke();
