If your problem seems to be the one I’m thinking about use this answer from askubuntu.com
I just switch to silverblue yesterday and first that seems to be really cool. I’m really a fan of fedora and this immuable one is really nice. But with this particularly you couldn’t use the answer shown above (in fact some devices are authorized to wake up the device so it’s why it auto-reboot), because you could change anything in /usr I’m actually trying to find a way to resolve it but for now I couldn’t find… Tell you more once found! 🤞
