Answer 1

Why would you want to create it in config file? Do you want to edit module's configuration settings? If so, you need to do that in system.xml like shown below :

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
 <system>
 <tab id="fme" translate="label" sortOrder="250">
 <label>Vendor</label>
 </tab>
 <section id="vendor_module" translate="label" sortOrder="130" showInDefault="1" showInWebsite="1" showInStore="1">
 <class>fme-separator</class>
 <label>Article</label>
 <tab>fme</tab>
 <resource>Vendor_Module::resource_name</resource>
 <group id="general" translate="label" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
 <label>General</label>
 <field id="enable" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
 <label>Module Enable</label>
 <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
 </field>
 </group>
 </section>
 </system>
</config>

It'll make a Module Enable/Disable toggle in your module's configurations. Look under label "General" and in your config.xml you can set default value for this field like below :

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">
 <default>
 <vendor_module>
 <general>
 <enable>1</enable>
 </general>
 
 </vendor_module>
 </default>
</config>
