Magento 2 CLI – Disable All Custom and Third Party Modules with Single Command

As of Magento 2.2 the admin System Configuration Panel "Advanced" has been removed.

The following gives reference on how to disable a module's output.

https://devdocs.magento.com/guides/v2.3/config-guide/config/disable-module-output.html

In your custom theme, follow this to override the layout file

app/design/frontend/Theme_Vendor/Theme_Name/ThirdPartyVendor_ModuleName/layout/file_to_override.xml

After doing this, remove the static files and flush the cache

1. rm -rf pub/static/*
2. php bin/magento setup:static-content:deploy
3. php bin/magento cache:flush

There is an alternate way, which may works for you. You just need to create an custom module and inside module.xml add the dependency like

    <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Vendor_Modulename" setup_version="2.1.7">
        <sequence>
            <module name="ThirdParty_ModuleName"/>
        </sequence>
    </module>
</config>

Now you have to override the xml file as

app/code/Vendor/Module_Name/view/Scope/layout/file_to_override.xml

Scope can be either frontend or adminhtml (for backend)
