Keep cache disable while changing any XML file


Create xml file in your custom theme app/design/frontend/Custom/mytheme/Magento_Customer/layout/customer_account.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
