Error 43 when I virtualize Windows 10 with Bhyve on FreeBSD 13R + pass thru of my Geforce RTX 2080 ti inside the VM

Hello to everyone.

I’m on FreeBSD 13R and I’ve virtualized Windows 10 with Bhyve. I’ve also passed thru to the VM my Geforce RTX 2080 ti. It is detected by WIndows 10 but I get the error 43. I shouldn’t get it,because on the websites below I’ve read that starting from the NVIDIA Game Ready Driver 465.89 the virtualization on the Geforce is supported.
