Hello
There is no hook in this section in this file
/design/themes/responsive/templates/views/checkout/components/cart_content.tpl
You can either comment on this piece of code
<div class="buttons-container ty-cart-content__top-buttons clearfix">
<div class="ty-float-left ty-cart-content__left-buttons">
{include file="buttons/continue_shopping.tpl" but_href=$continue_url|fn_url }
{include file="buttons/clear_cart.tpl" but_href="checkout.clear" but_role="text" but_meta="cm-confirm ty-cart-content__clear-button"}
</div>
<div class="ty-float-right ty-cart-content__right-buttons">
{include file="buttons/update_cart.tpl" but_id="button_cart" but_name="dispatch[checkout.update]"}
{if $payment_methods}
{assign var="m_name" value="checkout"}
{assign var="link_href" value="checkout.checkout"}
{include file="buttons/proceed_to_checkout.tpl" but_href=$link_href but_meta=""}
{/if}
</div>
</div>
or overwrite this file with its own code

Robert.
