1. Is the SSD NVME enabled? Product description page says it is, but I see no option to switch from AHCI in BIOS. 2. Are there multiple BIOS/UEFI in this system? I can't get to it with any key press before Windows starts. 3. What are my options to expand storage? Spare 2.5" bays and M.2/PCIE slots? 4. Option for Intel XMP in BIOS? Alternative to tweak memory? 5. The GTX 1070, is it the "mobile" version or the "regular" version? 6. Can i7-8750H performance be enhanced? Overclocked? Recommendations for clocks and voltage? 7. Recommendations for tweaking GTX 1070?
