Can I adjust AMD fan curves on Opencore?

I have two drives dual-booting with Windows and MacOS. On Windows the GPU fans are usually not running at all in idle/normal use state. However, on MacOS the GPU fans spin up and down in regular intervals of about a minute. Is there anything I can do about this -- perhaps tweaking fan curves? I'd rather have them running all the time instead of turning off, if that's the only option.
