The thing comes with much bloatware which he will not need.
My most recent Dell W10 laptop arrived with McAfee Av installed, along with the other things which Dell thinks we need - including MS Office 365.
I removed McAfee (not easy, but I looked through the Goggle suggestions first), installed Avast and Classic Shell, and a previous version of MS Office. It has been a functional and satisfactory machine ever since. I subsequently removed the MS Office 365 suite after the warranty had expired. This was tricky, but I triumphed after a bit of perseverance.
I would be most reluctant to format the HDD of a brand new computer - especially a laptop - and expect a re-installation of the OS and the supporting software to be plain sailing. It may well turn out so to be, but I wouldn't go there. I also suggest that any warranty for the machine could be voided by such an action.
FWIW
