Ok sounds like you've got yourself in a bit of a mess.
So go back to the beginning and proceed in order.
1) Remove any third party kexts from your system. Reset your Pram.
2) Now verify that theres nothing wrong with the sintech adapter. Go into system profiler and check that the nvme drive shows 4x lanes running, not 2. If there was a problem with the pins not being properly taped you'd see frequent crashes upon waking the computer or you might see the ssd operating with only 2 lanes running. Checking with istats, your ssd should be reading around .16, .17A idle.
3) If everything is fine here, go ahead and install ssdpmenabler. You don't need the terminal commands. Just use hackintool, use hackintool's function for installing kexts. Then go to security preferences and 'ok' the third party extension. The system will want to reboot.
4) Reboot into recovery mode, open terminal and execute "csrutil enable --without kexts"
5) Reboot. Verify that ssdpmenabler is installed in the system profiler / extensions. Verify with istats that your idle reads around .06A
6) Now repeat the process with both Lilu and Nvmefix. Use hackintool to install, go to security pref., and reboot.
7) Again with verify that the extensions are loaded in the profiler, and check idle with istats, should be below .01A
All of this assumes you are using the intel 660p, a macbook pro 11,5, latest versions of ssdpmenabler, nvmefix, and lilu, and Monterey 12.1.
