M17 R4 Choosing the boot drive on initial setup

Hi all, I'm waiting for my new M17 R4 in a couple of weeks. It will come with 2 SSD 512Gb in RAID0 = 1Tb Drive and a third 512Gb SSD stand alone.
On Dell site, it's mention that the 1Tb RAID0 drive is the boot drive (windows) and the stand alone 512Gb drive is the storage one.

My question is, Is it possible, at the initial setup, to set the 512Gb as the boot drive (windows) and the 1Tb RAID0 drive as the storage drive?

Thanks in advance
