Move SSD into the same IOMMU group as the second GPU

I have a working Qemu configuration with GPU-pass-through. Now I would like to pass also a SSD to the quest. I have read that the pass-through-devices should be in the same group. The following script: ~~~bash #!/usr/bin/env bash shopt -s nullglob for g in /sys/kernel/iommu_groups/*; do echo "IOMMU Group ${g##*/}:" for d in $g/devices/*; do echo -e "\t$(lspci -nns ${d##*/})" done done ~~~ Shows that my GPU is in group 8, but the SSD is in group 9. ~~~none IOMMU Group 8: 01:00.0 VGA compatible controller : NVIDIA Corporation TU117 [GeForce GTX 1650] [10de:1f82] (rev a1) 01:00.1 Audio device : NVIDIA Corporation Device [10de:10fa] (rev a1) IOMMU Group 9: 02:00.0 USB controller [0c03]: Advanced Micro Devices, Inc.

I used already driverctl set-override 0000:05:00.0 vfio-pci to change the driver from nvme to vfio-pci, but this does not change the IOMMU group.
