If you would like to completely disable the side cart, or drawer, from appearing when the cart button is clicked, you could go to Theme Editor and select the header.liquid file under the Sections folder.
Around line 15 you'll find the following:
<a href="#cart" class="icon-cart right">{% if cart.item_count > 0 %}<div class="cart_count">{{ cart.item_count }}</div>{% endif %} <span>{{ 'layout.general.cart' | t }}</span></a>
Which can be updated to:
<a href="/cart" class="icon-cart right">{% if cart.item_count > 0 %}<div class="cart_count">{{ cart.item_count }}</div>{% endif %} <span>{{ 'layout.general.cart' | t }}</span></a>
Then around line 223 you'll find the following:
<a href="#cart" class="icon-cart cart-button">{% if cart.item_count > 0 %}<div class="cart_count">{{ cart.item_count }}</div>{% endif %} <span>{{ 'layout.general.cart' | t }}</span></a>
Which can also be updated to:
<a href="/cart" class="icon-cart cart-button">{% if cart.item_count > 0 %}<div class="cart_count">{{ cart.item_count }}</div>{% endif %} <span>{{ 'layout.general.cart' | t }}</span></a>
The cart button will now link directly to the Cart page.
