Your system uses a custom blade SSD which happen to be made by Samsung for Apple, while similar to a M.2 SSD it is not pin compatible. Your system has a AHCI/PCIe x4 (4 lane) interface.

I would recommend you stick with the correct drive made by either OWC or Transcend. Both make replacement SSD's designed to work in your system.

I'm not sure I understand what you're saying here. There are mechanical & physical limits within your system. The issue is not software you can only use a AHCI/PCIe SSD not a NVMe/PCIe SSD.

Think of it like gasoline and diesel fuel they both run cars & trucks but you can't use one fuel for the other.

@fooad444 - Apple was ahead of the curve with blade SSD's.

The issue you're facing is just the speed of change! AHCI based systems are still being sold from Dell and Lenovo. But, the move is on to NVMe/PCI for the upper end systems!

All of the 2016 and newer Mac's use NVMe drives. In fact Apple's new iMac Pro is using interleaved raw flash which is even faster than NVMe based SSD's!
