Not related to selfhosted but OK.

Don’t know about such software for Windows, but if you run Windows on a virtual machine on Linux, like virt-manager/libvirt you can add the USB as a local SSD.
Virt-manager isn’t the most user friendly, but have a lot of features

I only use PiHole for a couple of months, it wasn’t easy to setup something that worked on my LAN and over internet. Initially I used OpenVPN but was hard to use it with profiles to identify the devices.

Than a tried AdGuard Home, and use it with DoH/DoT server was very simple, and can easily use any profile for each device on LAN or DoH/DoT server.
Can easily search logs and block/allow for each device.

Give it a try, and use it for a couple days.

Just one thing, must be indefinitely not 48h, otherwise nothing will change. A year have 365 days, 48h it’s a weekend, if subreddits come back after 48h it’s nothing happened.
