How can I hide departments in the left menu of Bitrix?

Question

1C-Bitrix

There is a list of departments (made as a website). Is it possible to remove them from the left menu, not hide them through the settings in the public part, but delete them.

Answer 1

I figured it out by poking.
Need to hide, remove in .top.menu_ext.php

$arMenuB24[] = array(
            htmlspecialcharsbx($site["NAME"]),
            htmlspecialcharsbx($url),
            array(),
            array(),
            ""
);

Answer 2

In admin mode, edit the menu in the public part and apply for everyone
