Any fault history available?
Compare signals voltage with good board.
As last option, you can consider to replace with M2 NVME SSD.

The MacBook was erased for sale, but when I tried to install a clean system, the disk was not detected!
I bought an identical board on which the system is installed, but it only works for an external display and I removed the SSD from it without receiving the SSD, I transferred the S3X and still no SSD. Is it possible that the problem is in the Thunderbolt? I only get two 3.3V voltages for a moment and then disappear, but they should stay there, or am I wrong?
TBT_T_CLKREQ_L=3.3v and immediately zero
SSD_PCIE_CLKREQ_LB_L=3.3V and immediately zero

SSD is connected directly to PCH; not related with TBT.
I'm not sure about SSD_SR_EN_L voltage.
