How can I disable .form-label on a specific product page?

Hey, so I have a product page where I want to make the .form-label invisible, more specifically, this:

“fieldset.product-form__input”

I’ve tried putting this code on the theme.liquid file, but it doesn’t work

{% if page.handle == 'full-nutrition-plan-bundle-1-training-plan' %}
    
  {% endif %}

Could you please help me out? thanks a lot!
