Will Reset to non-optane (according to most ASUS ROG Laptop) deletes entire data on both HDD and Optane?

I was installed a new BIOS of my ASUS R9G GL503GE by Windows Update. Unfortunately, this procedures resets the Disk controller mode to AHCI where is should have been stayed on Intel RST / Optane acceleration. Because of this, Windows becomes unable to boot, BSoD with message: INACCESSIBLE_BOOT_DEVICE Now I have changed back the disk controller back to Intel RST / Optane Acceleration. However BIOS is unable to boot the Windows. I have read an article here I have cleaned the Optane. Still no effect. There was an alternative option on the article, to Reset the disk to non optane over the BIOS. After I chose the option, there was a message that freaks me out: "delete the data on BOTH disks..." Horror message, delete data, entire data? Sure, this is what makes me get stuck. I need to decide. Does this delete all data on my HDD? The HDD contains important document and may not lost under any circumstances.

Thank you for your attention.
