Did you replace your GPU with the K2000M ?
Your SUBSYS is supported but with the 5010M and K3000M
What you could do is edit the nvcvwi.inf and edit the K3000M change the PCI_ID to K2000M and it should work
Change both the start of the INF (OS selection) and end of INF
Or just force an install for the K3000M by unselecting show compatible devices in Device manager driver update.
Only advice is stay with Dell FW, only controller where this makes sense.
The Dell has slightly different HW to the LSI and here you are getting unstuck
The Chenbro expander (I take it is not being seen) is a bummer
Just get a LSI9260 or equivalent to replace the H700, then you'll be sorted and sell the H700
