Hi @tkruger, you can set your own variable to be equal to “standard_header_includes”, then loop through every line in the variable and if it includes the CSS file then don’t add it to your template.
Something like this:
{% set custom_header_includes = standard_header_includes|split('\n') %}
{% for line in custom_header_includes %}
{% unless line is string_containing 'the-file-to-exclude.css' %}
{{line}}
{% endunless %}
{% endfor %}
By doing this you would be adding all the necessary code except the CSS.
We do something similar in several of our pages and it works for us.
Hope this helps!
