You need to create default a configuration for your admin items in

app/code/VendorName/MyModule/etc/config.xml
<default>
<section>
 <group>
 <field>{value}</field>
 </group>
</section>
</default>

For example:

<?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>
 <section_id>
 <group_id>
 <my_boolean_option>1</my_boolean_option>
 </group_id>
 </section_id>
 </default>
 </config>
