Hello,
Welcome to Microsoft Q&A!
There is no method to set space between tab items , but as a workaround , you could use TabWidth
to divide the width of the entire screen according to the number of the tab items , in this way you don't need to scroll the tab to show all items.
//xaml
<xct:TabViewItem TabWidth="{Binding TabWidth}"
//code
var actualWidth = DeviceDisplay.MainDisplayInfo.Width / DeviceDisplay.MainDisplayInfo.Density;
TabWidth.TabWidth = actualWidth/ItemNumber;
