I suggest you could refer to the Doc:TabView Class

You can modify the default Style and ControlTemplate to give the control a unique appearance. For information about modifying a control's style and template, see XAML styles. The default style, template, and resources that define the look of the control are included in the generic.xaml file. For design purposes, generic.xaml is installed with the WinUI (Microsoft.UI.Xaml) NuGet package. By default, this location is \Users<username>.nuget\packages\microsoft.ui.xaml<version>\lib\uap10.0\Microsoft.UI.Xaml\Themes\generic.xaml. Styles and resources from different versions of WinUI might have different values.

I suggest you could try it by yourself first. If you have any further question please let us know.
