Disabling GPU fans

I've installed Catalina and I'm using my onboard graphics Intel HD 530, but I also have a dedicated GPU which is a GTX 980ti. The fans keep spinning on it while in macOS, and I'm aware of no support for web drivers but is there a way to turn the fans off? I've tried the boot arg "-wegnoegpu" and I've also tried the DeviceProperties Method but didn't seem to work. Am I doing something wrong?

Here's my plist file: https://filebin.net/wbxx12owyn5rmn3m
