2 ways to do this:

1. Remove 'catalog.topnav' from Block 'store.menu' and add your own custom topnav block, In the block you will want to add your logic on how you want your mega menu build
2. Create helper class in Vendor/Module/Helper/Data.php, in this class build your architecure the way you want it then, simply override the template for 'catalog.topnav' like so:

<referenceBlock name="catalog.topnav">
    <arguments>
        <action method="setTemplate">
            <argument name="template" xsi:type="string">Infinri_MegaMenu::topmenu.phtml</argument>
        </action>
    </arguments>
</referenceBlock>

then set up your template as needed ex:

<?php declare(strict_types=1);

use Magento\Theme\Block\Html\Topmenu;

/**
 * Custom Top Menu template for Mega Menu
 *
 * @var $block Topmenu
 */

// Fetch categories using your custom helper
$helper = $this->helper('Infinri\MegaMenu\Helper\Data');
$categories = $helper->getFormattedCategories();

// Core menu rendering logic
$menuTree = $block->getMenu(); // Use if/as needed
?>

<nav class="navigation" data-action="navigation">
    <ul class="menu" data-mage-init='{"menu":{"responsive":true, "expanded":true, "position":{"my":"left top","at":"left bottom"}}}'>

        <?php foreach ($categories as $category): ?>
            <li class="level0 nav-item">
                <a href="<?= $block->escapeUrl($category['url']) ?>" class="level0">
                    <?= $block->escapeHtml($category['name']) ?>
                </a>
                <?php if (!empty($category['children'])): ?>
                    <ul class="level0 submenu">
                        <?php foreach ($category['children'] as $childCategory): ?>
                            <li class="level1">
                                <a href="<?= $block->escapeUrl($childCategory['url']) ?>" class="level1">
                                    <?= $block->escapeHtml($childCategory['name']) ?>
                                </a>
                                <!-- Add deeper levels here if necessary -->
                            </li>
                        <?php endforeach; ?>
                    </ul>
                <?php endif; ?>
            </li>
        <?php endforeach; ?>

        <?= /* @noEscape */ $block->getChildHtml() ?>
    </ul>
</nav>
