Thied literally everyting, from 100+ attempts saw it twice only in BIOS.
CSM disabling, both M.2 slots, via PCI NVME adapter, via PCI-e NVME adapter, without any other drives, with SATA disabled in BIOS, BIOS reset, BIOS upgrade. All slots works fine, currently 512 + 256 NVME installed.
Drive itself works fine, tested in other PC. Can connect to my PC only via USB3 external enclosure, but it's not role I purchased 1Tb NVME for...


Please, any ideas what else can I try?
 
I'm assuming you flashed the BIOS in order to troubleshoot the SSD issue, did you clear the CMOS after verifying your BIOS was flashed successfully?

Ideally you're advised to disconnect from the wall and display, then remove the CMOS battery, press and hold down the power button for 30secs to drain any residual power, then reseat the CMOS battery after 30mins.

M.2 2280 1TB Kingston (SNV2S/1000G)
That drive is PCUIe4.0x4, the most your platform's slots will operate at is PCIe3.0x4 speeds, even if the drive/slot is backwards compatible, you should've looked into a PCIe3.0x4 drive to make sure you didn't run into compatibility issues. As it stands Crucial, Samsung and Usually Kingston PCIe4.0x4 drives have been having issues on older platforms even though they shouldn't.

That being said, I'm assuming it's a BIOS/motherboard issue as the drive is recognized via an external enclosure.

Not exactly, I've updated BIOS earlier, when added discrete GPU - just for sure.
I've tried to clear CMOS, didn't helped.

Oh my, that was exactly thing I'm afraid of. Shop didn't refund/exchange operational devices, seems I need to search for some stuff to exchange on second-hand market. Worst thing is this Kingston successfully detected by 12 years old ASRock 970 Pro3 R2.0 via PCI adapter.
