Interesting. I never passed the rom option to my 2080 ti and it works fine with windows 10. In January 2020 I was using qemu-4.0, since then I swapped a few versions of qemu till 5.1 and it works fine without the rom option. I use intel CPUs though. I wonder if that's the difference. I use edk2-ovmf though. I wasn't able to get it to work with seabios.
