i've enabled IOMMU in BIOS & also enabled IOMMU mode as 64MB but same issue.

while VM is in power off state it displays like this:

First you need to configure the device as pass through device on host and reboot. Only then you can add it to the VM

Make sure the device you are configure as pass though is the supported one
