Javascript Deactivate some lines in a script

Question

In a website, there is a js file like:

<script src="/somescript.js"></script>

somescript.js includes:

<script> 
 function hi(){alert('Hi');} 
 function sup(){alert('Sup!');} 
 hi();
 sup();    
</script>

When I enter the index page, my browser automatically runs the function hi()

How can I prevent browser to run the function hi() or change it into something i want.

Website is not mine.

Thanks

There is no chance that browser launch a function by itself. You must have a <script>hi()</script> somewhere in index page — Bertrand

I don't think there's any way to do this. You might be able to write a browser extension that prevents loading somescript.js entirely, but I don't think it can selectively deactivate parts of it. — Barmar

This will call the functions, the need to be removed from the script if you don't want them run.

 hi();
 sup();

You can also specify functions as exports and import them as show in this answer.

He can't change the script, it's not his website.
