Basically the anchor is generated by the MVC wrapper which uses the Html helper to generate links and I am afraid it is not possible to change the rendering behavior.
On which browser does this exactly happen? I tried the offline MVC demos and on Internet Explorer 10 it does not seems to make the browser jump up and down when click on the tabs. Also you can try to prevent the default behavior of any link inside the tabstrip.
//when the tabstrip is initialized
If possible give a sample project and concrete instructions so we can search for a resolution.
