Answer 1

Try this:

{% if role == 1 %}
    <div id="cabecera">
        <header class="py-3 mb-4 border-bottom">
            <div class="container d-flex flex-wrap justify-content-center">
                <a href="/home" class="d-flex align-items-center mb-3 mb-lg-0 me-lg-auto text-dark text-decoration-none">
(...)
{% endif %}

You don’t need the {{ }} to refer to variables inside Jinja statements. See here.

So provided you have passed a variable role to the template the following will work:

{% if role == 1 %}
        <div id="cabecera">
       etc...
{% endif %}
