Answer 1

For this, you need to Create a System.xml in the folder like etc/adminhtml/System.xml

<?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="ModuleName" translate="label" sortOrder="10">
           <label>ModuleName</label>
       </tab>

      <section id="customproductdata" translate="label" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
          <class>separator-top</class>
            <label>Custom Product Data</label>
                <tab>ModuleName</tab>
    <resource>ModuleName_Customproductdata::customproductdata_configuration</resource>
            <group id="general" translate="label" type="text" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
            <label>General Configuration</label>
           <field id="enable" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
          <label>Enable</label>
         <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
     </field>
   </group>
 </section>
</system>

 
Than Create Config.xml file as the Same location and Put Below code into that.

<?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>
     <customproductdata>
       <general>
           <enable>1</enable>
              <title>ModuleName Customproductdata</title>
         </general>
     </customproductdata>
 </default>
</config>

Now you will See this custom Yes no option in Magento 2 admin section.

Add the following content to have enable disable module configuration.

<?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>
    <section id="yourmodulename" translate="label" sortOrder="150" showInDefault="1" showInWebsite="1" showInStore="1">
        <resource>Vendor_YourModuleName::configuration</resource>
        <group id="general" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="0" showInStore="0">
            <label>Configuration</label>
            <field id="enable" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
                <label>Enable Module</label>
                <source_model>Magento\Config\Model\Config\Source\Enabledisable</source_model>
            </field>
        </group>
    </section>
</system>
</config>

Answer 3

Add below code in etc/adminhtml/system.xml

<group id="general" showInDefault="1" showInWebsite="1" showInStore="1" sortOrder="20">
<field id="enabled" translate="label" type="select" sortOrder="10" showInDefault="1">
    <label>Enable</label>
    <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>    
</field>
</group>

Using below code in helper file.

public function isEnabled()
{
    return (boolean) $this->getConfig('namespace_modulename/general/enable');
}

And call this function whenever you want. That's it, i hope it helps!
