Formatted Samsung M.2 970 Evo Reinstallation of original Firmware on

Hi, I have a near new Samsung 970 Evo 250Gb M.2 Drive with which I am having problems. My motherboard is a Z370 Gigabyte Aorus Ultra Gaming 2.0 and I modified the Bios to accomodate the M.2 drive. First I disabled the the csm module, then changed the  secure boot option and finally key management to clear secure boot keys. After this the Bios would not recognise the M.2 drive at all.  I then decided that I would install Windows 10 instead on a normal mechanical hard drive. This I did without any problems. I was able to see that the M.2 was detected in Drive Management and I am now using this drive for additional storage only. In the meantime I believe that I may have formatted the M.2 drive and this MAY have been one of the reasons it did not show up and even does not show up in the Bios. Now I want to be able to reinstall the Firmware and drivers from the Samsung website to try again and use this M.2 drive as a Boot Drive. Can I do this?, please give me some constructive advice to be able to undent my Very Dented Pride. THANKYOU  Regards, Laurie
