I'm not sure what people are calling "clover screen" which in your case looks like a screen with a black background screen and drives appearing, while in the other cases I saw a light gray-background like with its cylinder-like drives, in the former case, in options, I found that the boot arg has already nv_disable=1 at the end of it, is it possible to encounter such?
Another annoying problem I'm experiencing is related to the check boxes you wanted to be Injected Nvidia Web flag(at multibeast), in my case I only got two options similar like yours, Inject NVIDIA, and NVIDIA web drivers boot flag, which one should I check. and unfortunately there's more, the web driver you asked is not supported in my macOS x, and so far I could only find web driver-378.05.05.25f01.pkg, which is perfectly compatible, but apparently not working properly, does AGDPfix work for this one, too?
