Thanks, I'll give it a try!
Honestly, I'm really surprised myself, that the iGPU passthrough works so smoothly. I've previously attempted to achieve the same with Proxmox and failed.
I've replaced the UUIDs and the MAC address in the config, let me know if I can help out in any other way. The host is a HP ProDesk 400 G5 Mini (https://support.hp.com/us-en/document/c06403257, with an i5-9500T CPU). Unraid is the latest stable (6.10.2) via the USB installer, VM client is a Fedora 36 netinst/everything. I've set up the VM with basically all the default settings, except the Graphics Card.
