I'm attempting similar thing, used the windows media creation tool to usb flash drive, with the amd raid drivers. In my case i wanted clean os install, but wanted to preserve prior windows in case it didnt succeed.
I have gigabyte x399 gaming 7 F11e bios, 5 samsung (1 evo 960 and 4 evo 970) in the raidxpert (with CSM disabled now and i needed 4x4x4x4x on my pcie for hyper m.2 so i now see the raidxpert2 config bios and no nvme config) - had to actually delete the 4 raid volumes it created itself somehow, and recreate a single 4 ssd raid 0 there. older windows was on the older ssd (no raid drivers), so i left that alone, so I could continue to boot it. But problem comes when now trying to clean install win10 os and getting blue screen upon loading the storport raid controller driver in the newinstall/recover load drivers as the gigabyte board manual states. it loads rcbtoom driver normal (10 seconds) goes back to screen with volumes (which all disappeared at that point), but trying f6 the load option again for the storport it shows up in list, and hangs (maybe 3 minutes) before finally blue screen or in this last case just findally came back after 5 minutes with no volumes listsed at all (we couldnt find any drives).
The first attempt was with gigabits drivers, VERSION: RC-9.1.0-00018 12/5/2017. I then downloaded the amd version from amd site Revision: 9.02.00.087 Built date: 09/18/2018. but it's hanging the same way. the New Windows 10 from dlc seems to have dates of 10/29/19. (whichis after the amd drivers dates, probably not relevant to the problem). I forgot to mention I had a SATA magnetic hard drive raid 0 in there as well for data (and bios has sata raid enabled, not ahci). I did see that blue screen with watchdog error description when the drivers failed.
It got interesting when I tried removing my prior windows ssd (evo 960), just in case it was seeing that. suddenly it loaded the amd's storport driver, and populated the volume list, finding my unallocated 2 tb evo 970 array. and i was able to set it for win10 and continue install. I hope this helps other troubleshoot, but sounds like there is somethign going on with driver and backward compatiblity if it sees old windows drive. However after it copied files, it didnt boot , purple with mouse cursor and a hang :-/ then pressed reset and it started "Getting Ready", (breathe relief). then another reboot! (holding breath for spinning circles and laughing i'm old enough to remember hour glasses and please wait messages while it takes forever to say youre good to go). and then it says just a moment 
which is a good sign that you'll see the final "Hi!" and then "this might take several minutes"
After trying crystalmarks benchmark i'm only seeing 4124MB/s sequential read.. which sounds like the single drive speed of an 970evo, i was expecting at least a few times that. switching M.I.T. misc bios setting for slots from auto to gen3, seemed to improve to 5613 read, 5159 write, i can live with that i guess, I was just trying to evaluate if raid 0 was worth the trouble (it is at least to consilidate to 2TB).
