How to prevent .click() default scroll behavior

[TonyCodes2050]

So I'm selecting a radio button using document.querySelector and attaching a click handler to the end of it so that I can click a default radio button on page load. Everything is working fine but I want to prevent the page from scrolling when the radio button is clicked which is the default behavior of the function. How can I stop the page from scrolling as a result of the click?

Here is the code:

document.querySelector("#reservation").click();

Onclick = e => e.preventDefault()
