gpu passthrough dual nvidia card 1 for proxmox 1 for vm

[Hubby972]

Hello guys, i'm an new user of proxmox 6.2, I'm trying to use my 2 nvidia cards, one for the host (730 gt) and one for the vm (960 gtx).
I've try to install the vm (with windows 10) and it works! but time to time the host freeze because i can't blacklist all the drivers in order to make the host working ( because of it is two card from nvidia).
Is there anyone who have two nvidia cards like me and succeded in install one for the host (proxmox) and one for the vm? or may be, there a thread that could give me some help? I have search but no found any matches.
Thanks for the answer !

im new as well but i read so far that nvidia consumer cards like thier geforce series need special configuring to get working with iommu and hardware interrupt. thats all i looked into, i have a quadro so im hoping that hardware interrupts wont be an issue.
