ChromeCast add tag <script> for dpad controls

Question

I am using "ChromeCast HD". When loading the cast receiver I see an extra tag <script src="https://www.gstatic.com/cast/sdk/libs/caf_receiver/v3/cast_receiver_framework_controls_dpad_tv.js">‹/script> in my html.

I did not add this tag. I think the device is proxying the content and added this tag itself.

I also have a TV box with built-in Chromecast and the <script> is not added to the TV box.

How can I block the <script> from being added to my html?

Maybe it exists some 'CastReceiverOptions' that iI can use when Google Cast are starting?
