document.onscroll = () => {
    if(scrollY === 0){
    location.reload()
}}

The easiest solution will be to use js to click a link. Say that on the top of the page you have a div with id of top:

<div id="top">top section of page</div>

Then all you need to do in js is just to click on a virtual anchor element:

let a = document.createElement("a")
a.href = "#top"
a.click()

Then just call window.location.reload() to reload the page

I haven't tested this but the main idea works

function topScrollAndRefresh() {
  document.body.scrollTop = 0;
  document.documentElement.scrollTop = 0;
  setTimeout(() => {
      window.location.reload()
  })
}
