Hi @galaxyvitas1143
Here's the [https://dl.dell.com/content/manual45476405-xps-15-2-in-1-service-manual.pdf?language=en-us|service manual], taken from this support [https://www.dell.com/support/product-details/en-au/product/xps-15-9575-2-in-1-laptop/resources/manuals|webpage] for the laptop.
Go to p.52 to view the procedure to remove the ''palm rest and keyboard assembly''.
Basically you have to nearly completely disassemble the laptop to do this.
