Change Default Graphics card for boot

[jacobcooley797]

I have an RTX 2070 for my windows install and an RX570 for my Mac OS Mojave install. Clover seems to use the RTX 2070 as the default card for booting. In order to boot with the right card, I have to unplug the HDMI cable from my RTX 2070. Only then will the system boot using the Displayport cable connected to the RX570. how can I change it to use the RX570 by default instead.
NOTE: Both cards are connected to the same monitor, Nvidia to the HDMI and the Radeon to DP.

I tried a similiar approach for HD530 and my 980Ti.
I use HD530 as primary display to boot, using nv_disable=1, and in Windows I set to use only 980Ti (you can try to disable the device also, but in my case I had trouble to boot back on osx).
I manually switch form the monitor to DP (980ti) each time I boot Windows.
It works well.
