What is involved in disabling raid 0?

I'm considering buying an Alienware M17 R3, but it the only 2 SSD drive option is raid 0, which I am not interested in. I'd rather have the two drives as separate drives (such as partition C: and D:).

I'm a programmer, and I've had systems where I used raid, but replaced drives and didn't use raid. However this was done on generic systems, where I installed the OS myself.

For Dell systems, there's often a hidden partition used to "restore to factory settings".

So if I purchase the laptop configured as Raid 0, and I disable the Raid 0 (typically done in BIOS, but Windows also has a Raid option), what will I need to do? I assume I'll have to re-install Windows 10, but is bootable media included so that I can re-install Windows 10, and all of the required drivers, and any Dell specific programs that should be installed? I don't care about the hidden partition going away (if there is one).

Does Dell have some utility to automate the process of disabling Raid 0 without having to do a reinstall?

Ignoring the time factor, I'm thinking it would be simpler to leave the raid 0 as is, and backup (system image or files and folders) to an external USB 2TB drive, which I already do with my current system, even though it's slow. In this case I'd be concerned about system image restore, being able to boot Win 10 install or recover media, go into recovery mode and do an image restore from the USB drive (this could be an issue if a special USB driver is needed).
