Hello Stephan,
A year a go I did try passtrhu a dedicated nvidia GTX 1650 while using
integrated intel graphics (laptop Lenovo Legion 5 15IMH05). Windows
detected card but nvidia drivers install failed at some point.
On this laptop I did setup bios to use integrated graphics so I can
passthru dedicated nvidia.
Think I will give a new try since I follow main.
Are you using laptops for this usecase?
Thanks!

Hi!
You surely mean 'newer' NVidia cards, as my GT1030 works with FreeBSD
14.2 Host and ubuntu guest, NVIdia driver 570, (and Win guest btw)
out-of-the-box, no kernel/driver modding...
Regards,
Stephan

Hello!
Oh, laptops... With this "Optimus"-called feature i am not shure if it
will work...
But i think it's worth trying.
Maybe you will need the GPU ROM.

Good luck!
