Implementing Custom UI for IMA video ads

Hello is there a way to do this: https://developers.google.com/interactive-media-ads/docs/sdks/android/client-side/custom-ui

Basically tell AdsRenderingSettings to disableUI?

``` java
AdsRenderingSettings settings = mSdkFactory.createAdsRenderingSettings();
settings.setDisableUi(true);
mAdsManager.init(settings);
```

We are planning to customize the controls for the IMA ads container so we want to disable the default ad container of the IMA SDK
Thank you
