Radeon RX Vega 64 - dual monitor only with 1 hdmi

[iacopob]

I'm building a new hackintosh with this components:

i7-8700k
aorus ultra gaming wifi
Radeon RX Vega 64

Sys definition iMac 18,3

I'm having an issue with the graphics card, basically only the HDMI and 1 out of 3 displayports works.
This means I can plug 2 monitors only if one of the two is on HDMI, but I would like to plug both monitors on displayport.

Can this be fixed, or should I live with it?
