Blade Stealth, Windows Setup -- No Disks Listed

I'm running Manjaro Linux on my Blade Stealth 13" (I think the "early 2019" version -- CPU is i7-8565U). I want to re-install Windows on another partition. I've created a Windows 10 boot USB stick, and can boot and get to Windows Setup. However, there are no disks listed and I am prompted to load the appropriate drivers. I cannot find such drivers, can someone help with that?

Thanks!
