How do I run a powershell script when the unattend file runs?

Question

I am currently using filewave to deply windows and am going to use windows 11 this year. I am currently trying to figure out how to use the unattended file to run a powershell script to move the windows button to the left side of the screen automatically, along with removing all the extras on the taskbar, I have the script that I found that does these things, https://ccmexec.com/2021/10/modifying-windows-11-start-button-location-and-taskbar-icons-during-osd-autopilot/

However, I cannot find out what pass to put them on and how, any help is appreciated, thank you.
