R440 10x2.5 BP, NVME Cabling

Hello, I have a R440, that is cabled as such:

(Fig 1) https://www.dell.com/support/manuals/en-us/poweredge-r440/per440_ism_pub/cable-routing?guid=guid-ad7127ef-5446-4e8b-8036-47530c55ce27&lang=en-us

Is it possible to convert this to accept NVME U2 drives in the front bays? 

-I believe I need the L/R NVME Cable 2YPT8  & X6HJ6

-Can the PERC be moved to the rear riser slot, as shown in Fig 2?

-If yes, is a longer cable needed? - I see part # P54J2 , but i believe that is for a PERC11

Last, as I've done this before, but quite a while ago: If i only need to support 1 NVME drive in the BP, I still need to cable both L/R sides, or the BIOS will throw an error at boot, correct?
