What’s the Quickest Way to Wipe a Windows 11 System Drive?

What’s the fastest way to wipe the existing 2 TB SSD system and data drive (while leaving it inside the box)?

I’m sending a Lenovo laptop workstation into their repair depot to,

(a.) fix its growling fan(s) which started at 1 year and 2 days after the new machine was put into service, and,

(b.) add a separate, dedicated Windows 11 (Pro) system drive (512 GB?), which should also,

(c.) solve niggling, unresolved task scheduling/awakening problems with the original Windows 11 OS – after I used Laplink Pro to migrate both my data and apps from Windows 10.
