After switching to an intel a380 video card I am unable to access the BIOS / UEFI

To Reproduce
Reboot the PC connected to the PoKVM and don't see a video signal until the Windows login screen

Expected behavior
Expect to see a BIOS boot image with option to enter the BIOS and make changes

Screenshots
Not needed IMO

Desktop (please complete the following information):

OS: Windows 11
Browser: Chrome
Version: 116
VNC client: not used

PiKVM info:

Raspberry Pi 4 Model B Rev 1.5
hdmi
Intel A380
KVMD version: 3.121-1
uStreamer version: 5.16-1
Linux kernel: Linux pikvm 5.15.34-4-rpi-ARCH #1 SMP Tue Jul 5 12:10:16 MSK 2022 armv7l GNU/Linux

Additional context
This was working previously with a nvidia 1660
EDIT 1: I have tried all of the custom EDID options in this thread https://github.com/pikvm/pikvm/issues/78
EDIT 2: I just ordered a DP to HDMI cable since there are 3x dp and only 1x HDMI so I am guessing the first DP is only active until driver init, will post back later today when I find out.
EDIT 3: After update these are now the versions

kvmd 3.256-1
kvmd-fan 0.26-1
kvmd-oled 0.25-1
kvmd-platform-v3-hdmi-rpi4 3.256-1
kvmd-webterm 0.43-1

ustreamer 5.42-1

Intel A380 does require resizable bar enabled as well as using the DP connection for the first attempt to enable resizable bar.

Either enable this before installing your card or get a DP to HDMI cable like I had to do.
