How to make setting scrollTop scroll to the point instantly?

I’m trying to scroll to a certain block on page load like this (needs to work in IE 11):

getScrollbaleContainer().scrollTop = 
         block.getBoundingClientRect().top + 
         (window.pageYOffset || document.documentElement.scrollTop);

But Chromium browsers and Firefox scroll to that point with a duration. Is there a way to make it scroll instantly?
