I am recently creating a website for my company. I found there are many unnecessary markup by wordpress. I have provided screenshot and sample of the markup that i am referring to.

    </ol>
<!-- /wp:list --> <--this is one of the unnessary markup that i meant. There are so many and so on.

<!-- wp:paragraph -->
<p>*This package gives you the best experience as all swing doors/drawers come with soft-closing door hinges to ensure each door closes softly and quietly.</p>
<!-- /wp:paragraph -->

<!-- wp:heading {"level":3} -->
<h3>Upgrade to be Different</h3>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>This package, default is melamine abs. Bored of melamine abs? You have the option of upgrading the melamine to other door styles and worktop. Please read further. We have the best deal for the upgrade.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p><strong>Door style</strong></p>
<!-- /wp:paragraph -->

<!-- wp:list -->
<ul>

I’d like to ask if there is any solution to remove all these by inserting any php code to the functions.php?

Thank you!
