Hi,
There is no supported “extra cable” you can buy to re wire an H755 NVMe backplane to CPU PCIe directly; to get direct attach you effectively need the backplane/cable set for one of the S150/onboard NVMe configurations. Since those assemblies are tied to specific XR12 base configurations, We normally treat this as a field replaceable backplane/cable kit change rather than a simple upgrade cable, and part numbers for those kits are not published generically.
Recommendation for your use case
For caddies: order Dell 2.5" SFF carriers compatible with XR12, e.g. 85PPW/085PPW or whatever equivalent Dell lists against your service tag.
For bypassing the H755: open a Dell sales/support case with your service tag and request the “x6 2.5 NVMe (direct attach/S150) backplane and cable kit” for XR12, and ask explicitly whether conversion from your current H755 NVMe configuration to direct attach is supported; this is the only clean way to get CPU direct PCIe wiring without fighting undocumented proprietary cables

@DELL-Young E Can you explain me why should be replaced XR12 Backplane as is universal (Has all connector for SATA/SAS and NVME ports assembled). and is only Cables need?
This make no sense. Who can tell us the Cable set numbers? Even each cable is overpriced.

It depends on your XR12 configuration (2.5" or E3.S). Check your service tag on Dell’s support site or contact support to get the exact compatible part number.
