Change categories url in OpenCart version 3.0.3.7 - opencart

Question

I would like to change the urls for the categories. On my page, there are 4 categories: Home,Shop,About,Contact. For example, when I hit "Home", I want it to load the home page. Is there anyway to do that on OpenCart?
Edit:
This is the meu.twig:
{% if categories %}
<div class="container">
<nav id="menu" class="navbar">
<div class="navbar-header"><span id="category" class="visible-xs">{{ text_category }}</span>
<button type="button" class="btn btn-navbar navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse"><i class="fa fa-bars"></i></button>
</div>
<div class="collapse navbar-collapse navbar-ex1-collapse">
<ul class="nav navbar-nav">
{% for category in categories %}
{% if category.children %}
<li class="dropdown">{{ category.name }}
<div class="dropdown-menu">
<div class="dropdown-inner"> {% for children in category.children|batch(category.children|length / category.column|round(1, 'ceil')) %}
<ul class="list-unstyled">
{% for child in children %}
<li>{{ child.name }}</li>
{% endfor %}
</ul>
{% endfor %}</div>
{{ text_all }} {{ category.name }} </div>
</li>
{% else %}
<li>{{ category.name }}</li>
{% endif %}
{% endfor %}
</ul>
</div>
</nav>
</div>
{% endif %}
