Find the block class instantiated into a phtml file

Question

I need to modify a block class called in a phtml file, this is the customer.phtml file:

<?php
// @codingStandardsIgnoreFile

?>
<?php if($block->customerLoggedIn()): ?>
    <li class="customer-welcome">
        <span class="customer-name"
              role="link"
              tabindex="0"
              data-mage-init='{"dropdown":{}}'
              data-toggle="dropdown"
              data-trigger-keypress-button="true"
              data-bind="scope: 'customer'">
            <span data-bind="text: customer().fullname"></span>
            <button type="button"
                    class="action switch"
                    tabindex="-1"
                    data-action="customer-menu-toggle">
                <span><?php /* @escapeNotVerified */ echo __('Change')?></span>
            </button>
        </span>
        <script type="text/x-magento-init">
        {
            "*": {
                "Magento_Ui/js/core/app": {
                    "components": {
                        "customer": {
                            "component": "Magento_Customer/js/view/customer"
                        }
                    }
                }
            }
        }
        </script>
        <?php if($block->getChildHtml()):?>
       <div class="customer-menu" data-target="dropdown">
            <?php echo **$block->getChildHtml()**;?>
       </div>
        <?php endif; ?>
    </li>
<?php endif; ?>

I'm interested in the block beetween the div with class customer-menu. I want to remove <ul class="header link"> tag but not their li children, this ul tag is inside the <ul class="header link"> when someone is logged in.

You can check the Customer Block Class in:

Magento\Customer\Block\Account\Customer.php
