vulcaninfo, and some apps see 2 GPUs, when there is only 1

[jasoncollege24]

Dual-Boot
Primary: Kubuntu 22.04
Secondary: Windows 10
CPU: i9-9900K
GPU: NVIDIA RTX 2080SUPER (OC Edition)
iGPU: Disabled
SecureBoot: Disabled

At one point I had my iGPU enabled, but disabled it due to weird things it was doing. Long story short, the command

vulkaninfo --summary

shows the existence of 2 GPUs, when there is actually only one. This is causing errors or issues in some apps (like Lutris) that look for devices with Vulkan capabilities.

As far as I know, I don't actually have Intel GPU drivers installed, and the iGPU is completely disabled in the UEFI. Windows sees only the 2080 in it's Device Manager.

the command

cd /usr/share/vulkan/icd.d && for i in $(ls); do echo "====${i}====" ; VK_ICD_FILENAMES="$(pwd)/$i" vulkaninfo --summary; done

shows both the 2080, and the iGPU as GPU0

Edit: The command

lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA

shows only the 2080.

Is there a way to manually remove the unused iGPU entry from the list of available GPUs in vulcaninfo?
