You can use windows hello without biometrics.

I don’t believe there is any particular advantage of linux insisting on password input for privilege escalation. Obviously there is no proof of this, but I suspect that the design of this privilege escalation flow in linux is at least partly caused by its popularity as a server OS, for example the UI flow for Windows UAC wouldn’t work if you’re trying to remotely administrate a server through the terminal.

Is Windows + UAC + no password secure?

It should be, in fact I believe that by default if your local admin account doesn’t have a password set, remote logins and run-as is disabled for that account so you might even be able to argue that it is more secure. It’s probably one of the reasons why Windows 11 comes with a recommended option to disable passwords and only authenticate through Windows Hello.

You can generally pass through modern Nvidia GPUs as the entire device, provided that you let go of it in the host. It not supporting vGPUs just means you can’t virtualize and split up the GPU workload across multiple VMs, which I believe is also the case for consumer AMD GPUs as well.

For virtualization users, the driver addresses a soft lockup issue involving the vfio-pci module, which could occur after powering off a virtual machine with a passed-through NVIDIA GPU. This fix improves reliability for users running GPU passthrough in environments such as KVM or QEMU.
