Hi guys,
Today we continue to discover more Magento 2 tutorials on making the block visibility dynamic that is quite essential for adding module blocks to the layout.

As you already know, we can configure any block to display or not based on the Magento / Config / Model / Config / Source / Yesno configuration field by using the ifconfig argument. For the value, we can use XPath for the required field:
<block class="Namespace\Module\Block\Type" name="block.example" ifconfig="my/yesno/field">
...
</block>
For example: You check demo in the core contact module using ifconfig:
vendor/magento/module-contact/view/frontend/layout/default.xml
<referenceBlock name="footer_links">
<block class="Magento\Framework\View\Element\Html\Link\Current"
ifconfig="contact/contact/enabled" name="contact-us-link">
<arguments>
<argument name="label" xsi:type="string"
translate="true">Contact Us</argument>
<argument name="path" xsi:type="string">contact</argument>
</arguments>
</block>
</referenceBlock>
We also adjust the visibility by ACL Resource. Although it is primarily used in the admin area, the similar approach works for the frontend of the website.
<block class="Namespace\Module\Block\Type" name="block.example"
aclResource="Vendor_ModuleName::acl_name">
<!-- ... -->
</block>
