Enable Disable Custom Scripting Using SharePoint Management Shell

Introduction

With the latest version of SPO management shell, it is now easy to enable custom scripting on SharePoint online. Usually, this is needed when we are migrating the content from On-prem (2007/2010/2013/2016, etc) on SharePoint online as it needs some features to be migrated (like wiki, web parts, etc). Please note that when enabling custom scripting there could be potential impacts like

• Overutilization of resources could impact performance
• Access to resources that are more than intended

Also, you can’t audit where the custom script is injected. Please refer to references section, to understand the potential effects of custom scripting. As a workaround, MSFT recommends SharePoint framework for page customization in SharePoint online.
