Only displaying available options on shopify

In Snippets/product-form.liquid there’s a block of code:

<div class="swatch_options">
  {% for option in product.options %}
    {% include 'product-swatch' with option %}
  {% endfor %}
</div>

This is displaying options for products with X’s over the unavailable swatches:

<div data-value="option name" class="swatch-element color optionName-swatch available soldout">
  <div class="tooltip">Option Name</div>
  <label for="optionName">
    <span class="crossed-out"></span>
  </label>
</div>

When those non-compatible variants are clicked, a large “UNAVAILABLE” message is displayed:

<p class="modal_price" itemprop="offers" itemscope="" itemtype="http://schema.org/Offer">
  <meta itemprop="priceCurrency" content="USD">
  <meta itemprop="seller" content="site">
  <link itemprop="availability" href="http://schema.org/InStock"> 
  <meta itemprop="itemCondition" content="New">
  <span class="sold_out">Unavailable</span>
  <span itemprop="price" content="10.00" class="">
    <span class="current_price "></span>
  </span>
  <span class="was_price"></span>
  <span class="sale savings"></span>
</p>

I’ve tried checking for variant.available, product.variants.first.available, and variant.inventory_quantity > 0 before {% include 'product-swatch' with option %}, without success.

How do I hide the non-compatible variants?

Edit: Here’s what’s currently inside of product-swatch.liquid:
