can we use getServersideprops in any component in next.js

You cannot use getServerSideProps in non-page components. You can either pass the prop from Home to HomeSection or create a context so the value can be available globally from the component tree

getServerSideProps can only be exported from a page. You can’t export it from non-page files.
