SUCCESS!!!
Im happy to report that the MSI Prestige X570 Creation has a windows 7 compatible Bios. Windows 7 been installed and is fully functional expect for the intel wifi & Bluetooth devices which was expected based on other threads listed here and im ok with. NVME updates and USB drivers are functioning without issue. please note that for this motherboard i did experience issues with the 1.0.0.13 USB drivers causing USB sticks to malfunction when plugged into USB3.0 slots and not transfer data. This was fixed by switching to the 1.0.5.3 USB drivers provided by @canonkong (thanks!) and USB is working flawlessly with USB devices tested so far across all ports ( razer blackadder mouse, madcats kv5 keyboard, turtle beach stealth 450 headset, nexus 6 phone, and various models of USB sticks and portable hard drives)
now if only cyberpunk 2077 was as bug free as my system is…
