For this, you can create an extension. because you need to override files. First create file app\code\Vendor\Extension\etc\di.xml

<preference for="Magento\Sales\Model\Order\Pdf\Invoice" type="Vendor\Extension\Model\Rewrite\Order\Pdf\Invoice" />

Now override file app\code\Vendor\Extension\Model\Rewrite\Order\Pdf\ Invoice.php in function getPdf() use code

foreach ($invoice->getOrder()->getStatusHistoryCollection() as $status){
            $textChunk = wordwrap(strip_tags($status->getComment()), 120, "\n");
            foreach(explode("\n", $textChunk) as $textLine){
                if ($textLine!=='') {
                    $page->drawText(strip_tags(ltrim($textLine)), 35, $this->y, 'UTF-8');
                    $this->y -= 15;

For adding custom template to any block follow

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <referenceBlock name="order.comments">
        <action method="setTemplate">
            <argument name="template" xsi:type="string">Vendor_Extension::order/comments/view.phtml</argument>
