An element from system.xml can have a dynamic comment. The comment can be rendered through a model.
You need to declare the comment field like this:

<comment>
    <model>module/adminhtml_comment</model>
</comment>

Now you need to create the model with alias module/adminhtml_comment:

<?php
class Namespace_Module_Model_Adminhtml_Comment{
    public function getCommentText(){ //this method must exits. It returns the text for the comment
        return "Some text here";
    }
}

Do your magic in the getCommentText method and return the result.

Add into system.xml file

<field id="row_payment_us_free" translate="label" type="select" sortOrder="5" showInDefault="1" showInStore="1" showInWebsite="1" canRestore="1">
    <label>Payment US Free</label>
    <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
    <comment><model>VendoreName\ModuleName\Model\SystemConfigComment</model></comment>
</field>

app/code/VendoreName/ModuleName/Model

SystemConfigComment.php

<?php

namespace VendoreName\ModuleName\Model;

use Magento\Framework\UrlInterface;

class SystemConfigComment implements \Magento\Config\Model\Config\CommentInterface
{
    protected $urlInterface;

    public function __construct(
        UrlInterface $urlInterface
    ) {
        $this->urlInterface = $urlInterface;
    }

    public function getCommentText($elementValue)
    {
        $url = $this->urlInterface->getUrl('adminhtml/system_config/edit/section/payment');

        return 'Require to enable <a href="' .$url . '#row_payment_us_free" target="_blank">Zero Subtotal Checkout</a>payment method for Zero Subtotal order.';
    }
}

I Hope This Helps You.
