There seem to be a bunch of resistors missing too at least.

Oh, yeah. I see that now, to the left of the missing connector. I'm handy with a soldering station but I doubt I could solder those little SMDs.
If it’s ONLY the resistors and you magically know which ones: add solder to one of the pads, hold resistor with tweezers, melt solder with iron, push resistor into molten blob and position so it touches the second pad, remove heat so it’s frozen in place, then solder second pad.
Share a photo. Sometimes its just a missing connector, sometimes the controller or other bits are also removed.
I've soldered a sata connector and had it work, but everything else was still in place.
If there's a footprint for a connector but it's not populated it might be because they use the same board for multiple models with different CPUs, but the CPU you have only supports the one that's populated
I couldn't find where I saved the thread but people did this on a different lenovo model. you needed a bunch of resistors and the socket, plus depending on the board chipset it might be limited to sata only with the higher end chipset allowing for double nvme.
there was a chinese seller that had kits of the missing parts including the blue clip, plus the expansion slot that nobody knows what to do with that some boards are provisioned for.
