How do I change SATA Mode to AHCI instead of RST Optane in BIOS for Acer Aspire A515-54-79J5 Laptop?

I recently upgraded to Ver. 1.21 BIOS firmware (latest) installed. The HDD is an NVMe M.2 500GB drive with pre-installed Win10 and latest software updates. When I go into the BIOS, I am unable to switch SATA Mode from RST Optane to AHCI so I can dual-boot Win10 with MX-19 Linux since MX-19's installer cannot see the NVMe M.2 SSD drive with RST Optane enabled and thus cannot install Linux alongside of Win10. Please help.
