Debian bookworm - Is VDPAU really enabled

New install of Debian bookworm on a system featuring an AMD Radeon RX 6600 using the amdgpu driver. I installed vdpauinfo (sudo apt install vdpauinfo) and found a problem that is discussed in the [Arch wiki](https://wiki.archlinux.org/title/Hardware_video_acceleration#Configuring_VDPAU) .

Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
Error creating VDPAU device: 1

I'm surprised this isn't configured out of the box with bookworm (and I'm new to Debian). Am I missing something, or do I need to set the VDPAU_DRIVER environment variable (which is unset out of the box in my distro)?
