I don't think it will work, the key being what Barsik says here:
Your 980ti was never officially supported by any version of macOS, so which system kext are you going to use?
I also did not read in any source that my video card 9800 is officially supported by the system.
But, nevertheless, the video card was determined by the system drivers.
In this case, need past experience.
If there is no past experience, it can be resumed within one day, having tried all systems with the keys nv_disable = 0, Inject NVidia = yes without installing the WEBdriver от NVidia.
NVidia used to be traditionally well supported earlier in mac OS.
Therefore, there is a big chance to launch old video cards using the driver rollback to the previous version. Need to try different options. I did it quite easily in Mojave, despite the fact that my video card is almost 10 years old.
If this option does not work, then some other option will work. It is necessary to try ...
For example, with the old Chameleon loader on my old PC, Mojave booted as native with the same settings as 10.6.0. And the video card was defined.
But Clover did not fundamentally help determine the graphics card until I replaced in the system kext.
In English, unlike Russian, words are not enough to express a thought. Perhaps the closest word is "Grok" from science fiction writer Robert Heinlein. If you grokking the problem, the solution can be very simple ...
