Thanks for the answers. But I'm really sorry I didn't have knowledge to progress it even further. I don't know what to delete, or what to keep, and why.
For now I'm sticking with USBInjectAll.kext.
For
@ModMike, after reading
this thread I'we currently tried iMacPro 1,1 SMBIOS with this set to 0, and iGPU turn off in the BIOS, with PEG selected:

I will update for what effect this to my Catalina Build here:
1. DP /HDMI audio still problematic after some period of time. (I kind a give up at this problem, so lets skip this.)
2. With iGPU turn off at SMBIOS iMacPro1,1 my build didn't restart it self/glitchy after period of time, and I'm stress testing it hard:

This is recording Zoom call, playing YouTube video and compressor app rendering 30 minutes video.
3. There is some performance hit though:

But I will take the performance hit rather (3x slower) than nicer performance but the system restarting it self.
4. If I'm reading like 4 -6 thread about radeon VII problem (exp :
this thread), there is a way to enable the iGPU to working with iMacPro1,1 SMBIOS. but I'm not capable to understand that.
5. I'm trying nearly everything that I could, even re-sitting the build make sure everything connected properly. (exp: plug out and plug in the CPU, GPU, fan connector at the build, etc.)
6. I don't have moral of the story here, but I can say with
my build. SMBIOS iMacPro1,1 does provide most stable system.
7. Thanks for everyone helping me and others. Maybe, if someday
@ModMike change his GPU to Radeon VII, others and I with similar specs and similar limited knowledge, who also follow this excellent guide, can get fully working system. But, until then, this is as far as I can go.
8. I cann't stress enough, I'm thanking everyone that helping esp
@ModMike and
@Leesureone. You guys makes people like me can afford performance that Apple out-priced me longtime ago.
9. Good luck for everyone who still got a problems.
