Maximus Hero Motherboard Bios Update

Level 7
Hello guys,

I have used Rog Maximus X Hero (wi-fi AC) for 3 years and I recently updated BIOS for the first time through Asus EZ update software.

During the updates, the system automatically reboots 2~3 times, suddenly American Megatrends screen appeared and I saw the something like following messages.

Please enter setup to recover BIOS settings.
After setting up Intel Optane memory or the RAID configuration was built,
SATA Mode Selection must be changed to RAID mode to avoid unknown issues.
Press F1 to Run SETUP.

I pressed F1 and all my previous BIO settings were gone.

Is this normal for American Megatrends screen to appear with the message during the BIOS update?

Thank you.
