NUC9VXQNX failed to boot at logo with AMD RX5600XT gpu

[Toma]

Dear staff,

I purchase a new NUC9 and a powercolor 5600XT graph. When I plug the hdmi cable in the 5600xt, and start, the monitor show the intel nuc logo and reboot after a long time and continue the same condition. The problem is similar with this situation:https://community.intel.com/t5/Intel-NUCs/NUC-9-Pro-Kit-NUC9VXQNX-boot-loop-with-AMD-RX-5700-only-happens/m-p/1204401#M75945.

However, I already download the latest bios by QNCFLX70.0054.EBY.exe and install the amd bios and driver. I still cannot directly boot with my cable in the 5600xt. I need to plug the cable to motherboard hdmi port and start and when the windows interface appears and then plug the cable to 5600xt. It seems that the intel bios cannot verify the graphics card and boot normally. 

In addition, the front face two usb port usually not work properly and I need to use the back usb port. While I reboot, it works fine.

Toma, Thank you for posting in the Intel® Communities Support.

In reference to your inquiry and in order for us to provide the most accurate assistance on this matter, we just wanted to confirm a few details about your platform:

You mentioned that you are using the AMD RX5600XT card, I searched for the specifications of it and actually, there are different manufacturers for that card, could be Asrock, ASUS, MSI, who is the manufacturer of your AMD RX5600XT card?

By any chance do you have a link that you can share for us to be able to check the specifications of it?

How are you connecting the AMD RX5600XT card to the Intel® NUC, which ports are you using?

When did you purchase the Intel® NUC?

The problem with the front USB ports, is it recently or it happens since day 1?

If the issue with the USB ports is recent, did you make any recent hardware/software changes?

Please provide the SSU report so we can verify further details about the components installed on the Intel® NUC:

Just to let you know, I checked the list of tested peripherals for the Intel® NUC 9 Pro Kit - NUC9VXQNX and the AMD RX5600XT card was not listed, that does not mean the is not compatible is jut that it was not tested by Intel®:
