NVME device not found (likely because of a RAID configuration)
You're dealing with a laptop setup where Linux installation is failing due to NVMe drive detection issues. The presence of a PCIE RAID bus controller suggests the system is configured for RAID, which may be interfering with proper NVMe recognition. Since you can't adjust RAID settings in the BIOS, consider checking if a more advanced BIOS version is available for your Acer Aspire model. This could potentially unlock the necessary configurations to properly detect and manage the NVMe drive.
Some laptop bios settings might seem strange. I discovered them in the boot menu as well.
