Hi,
Did you mean this link?

You can use login_url
for that. – https://developer.wordpress.org/reference/hooks/login_url/
You can try adding this PHP code.
add_filter( 'login_url', 'my_login_linkchanger');
function my_login_linkchanger( $link ) {
$link = '?page_id=2';
return $link;
}
Just change ?page_id=2
value to your page slug. Ex: about/
, login/
, my-account/
Let us know if it works for you.
