The H10 module is a single sided design; all the components are built on one side of the PCB. Reading from the M.2 interface contacts back, the first IC is a Silicon Motion SM2263 controller, next to which sits a Nanya DRAM package, next up is the Intel 64-layer QLC 3D NAND which the SM2263 looks after.
Then there are the Optane parts of the package; an Intel SLL3D controller and a single Intel 128Gb 3D XPoint NAND package.
With the Optane part of the drive disabled it appears as an unknown disk, once enabled it becomes transparent to the system.
