Hi guys,
I have an AMD ryzen 2700x on an Aorus Gaming 7 wifi MB, 32Gb ECC RAM, a GTX1080 (I want to pass it through to the windows vm), a Radeon HD7730 (I want to pass it through to the TrueNAS VM to handle PLEX transcoding), and a LSI 9211-8i HBA, on which I'm trying to configure a home server that will run the next VM's:
1. TrueNAS scale vm, in which there will be Plex and Immich;
2. Home Assistant vm;
3. Windows vm;

I have the following problem: The HBA is plugged in the PCIe slot that is controlled by the chipset, and it is stuck in the same IOMMU group with all the devices linked to the chipset. How could I separate it from the IOMMU group of the chipset? (IOMMU and ACS are enabled in BIOS, also can't switch the PCIe cards between them because of clearance issues, besides that, then I would have to figure out how to pass-through the HD7730, which is more difficult from what I researched online, being a GPU)

This is my first time playing around with Proxmox, so yeah, I know I may seem stupid in this space.
