An did upgrade to Mojave as well. so running ok.
how to get tit to read the Hware of the card
I am not quite clear on what you mean by the above.
If you mean that whilst you can boot the Mac and login and use it with the W8100 but that Final Cut Pro rejects the card then it would seem Final Cut Pro is looking for particular models of card or it is looking for particular capabilities of video card.
Getting Mojave working is interesting, this card is not listed on Apple's list for the Mac Pro 2010 but of course when one thinks about it the Mac Pro 2013 is listed so the fact it is very similar to the Mac Pro 2013 video cards explains it. To confirm things open System Report and have a look at the Graphics/Displays entry and see what it shows - it should include Metal support.
Have you been able to spoof it being recognised as an AMD FirePro D500 or similar? (By editing the Kext.) I believe the W8100 is nearest to the D500.
Perhaps a similar modification of the Final Cut Pro app might work. If you right click on the App and show the package contents and look at the various plists you might find a similar list.
If you upgraded to Mojave after modifying the Kexts then your changes will likely have been overwritten.
