Do not show rollover when pinching to zoom or double tapping to zoom out

Hello,
I’m looking at the iOS “Sync Multi Chart” example that is referenced here:
https://www.scichart.com/documentation/ios/current/tutorial-07—linking-multiple-charts.html

Source code is here:
https://github.com/ABTSoftware/SciChart.iOS.Examples/blob/SciChart_v4_Release/SciChart.Examples/Examples/Examples2D/CreateMultiseriesChart/SyncMultiCharts/SyncMultipleChartsView.swift

When the user does a pinch to zoom gesture the rollover is shown.
When the user does a double tap gesture the rollover is shown.
How do I stop the rollover from showing when pinching to zoom or double tapping to zoom out?
thanks,
Charlie
