Make entry in nav not clickable and reroute

Question

I have an entry that acts as a parent to several children pages. Trying to make so that particular parent isn't clickable AND reroutes to homepage if address url is accessed.

Not sure if I can work something into existing nav code or if this needs to be done somewhere else, but here's the code, nonetheless. Thanks in advance.

<ul>
    {% set pages = craft.entries.section('page') %}
    {% nav page in pages %}
        <li>
            {{ page.getLink() }}
            {% ifchildren %}
                <ul>
                    {% children %}
                </ul>
            {% endifchildren %}
        </li>
    {% endnav %}
</ul>

You can use the level method to determine which iteration of the nav you are on and change the behavior:

<ul>
    {% set pages = craft.entries.section('page') %}
    {% nav page in pages %}
        <li>
            {% if page.level == 1 %}
                <a href="/">{{ page.title }}</a>
            {% else %}
                {{ page.getLink() }}
            {% endif %}
            {% ifchildren %}
                <ul>
                    {% children %}
                </ul>
            {% endifchildren %}
        </li>
    {% endnav %}
</ul>

of if it's only one particular entry, then you can create a conditional to check for that entry (using slug, id, title, or any other attribute or field value).

<ul>
    {% set pages = craft.entries.section('page') %}
    {% nav page in pages %}
        <li>
            {% if page.slug == "myPage" %}
                <a href="/">{{ page.title }}</a>
            {% else %}
                {{ page.getLink() }}
            {% endif %}
            {% ifchildren %}
                <ul>
                    {% children %}
                </ul>
            {% endifchildren %}
        </li>
    {% endnav %}
</ul>

If the url is accessed directly you can add a redirect to the template.

{% if entry.level == 1 %}
    {% redirect siteUrl %}
{% endif %}
