Issue with unsigned AMDRadeonX3000

[ovidoi]

Hi, 2 days ago I managed to install Mac os Mojave on my laptop from Alienware, 
I had recently installed High Sierra and everything was 
going very well including Wi-Fi and Video Qe-Ci, but in Mojave 
I have a problem with video acceleration more precisely AMDRadeonX3000.kext
which cannot load it because it has a problem with the certificate, 
the other related kexts do not have this problem, I have attached some
screenshots to see, please help me, Mojave works faster, it loads with 
the same EFI from High Sierra, Sleep and Wake is a bit faster than
its predecessor, the video card is recognized correctly as in High Sierra, 
the AMDRadeonX3000 file is the latest build that they took out
of Monterey and downloaded .pkg from Github. What can I do to get the s.o.
to load it in kextcache, thanks in advance.

here is the files for non metal card terascale :https://github.com/dortania/PatcherSupportPkg
