The Optane Memory Driver (which I'm certain I don't need; have no Optane hardware) went into BIOS and changed the SATA Mode Selection from AHCI to Intel RST Premium With Intel Optane System Acceleration. That's why my drives disappeared. Didn't even know it was possible to change BIOS settings outside BIOS. There's several drivers on Gigabyte website that do appear to be relevant to my system. I began to install them all, but I'm not going to install any now. I saw no evidence of hardware issues in any this. I'll restore the image and proceed with the in-place update.
