Strange thing. tried again from the beginning. In the BIOS, I left SATA in AHCI mode (before that stood in raid), and nvme as raid. I got to the driver installation and this time I could not install anything from the nvme_did folder, the list was empty, like "incompatible with my equipment". But from the nvme_cc folder (for a different processor) - success, and one disk appeared! While everything seems to be established and working, I observe.
