Kaltura DualScreen - Is it possible to enable or disable the second screen at runtime?

The Kaltura player allows the “dualScreen” plugin via runtime uiVar configuration (through flashvars). Is it possible to enable or disable the second screen at runtime?

kWidget.embed({ flashvars: { “dualScreen”: { “plugin” : true }}})

Specifically, I would like to force displaying a dual screen Kaltura player on the iPhone.

Example of dual-scren player: http://player.kaltura.com/modules/KalturaSupport/components/dualScreen/tests/dualScreenTest.html

With Kaltura HTML5 player Version 2.89, the second screen of the dual screen configuration is not shown by default when the browser uses the iPhone UA.

(e.g., UA=“Mozilla/5.0 (iPhone; CPU iPhone OS 13_3_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0.5 Mobile/15E148 Snapchat/10.77.5.59 (like Safari/604.1)”).

Is there a way to run some javascript code that forces displaying the second screen at runtime?

Thanks
