Updated tonight on Kubuntu Plucky (Debian sid isn’t bleeding-edge enough for me), through KDE Discover. This is the first time I’ve seen a firmware update through Discover and I must say it’s pretty cool!
The update went smoothly, though afterwards my particular monitor setup was acting a bit funky. Specifically, an external 4k monitor that was connected via a USB-C to DisplayPort adapter was unstable. Disconnecting and reconnecting resolved that, but it got me rejiggering my monitors to discover that my docking station now works in different configurations. I still can’t reliably get dual 4k outputs from it with Wayland (comment about Linux kernel 6.13-rc1 upcoming though - I’m currently on an Ubuntufied kernel 6.11), but I can now use one output attached to it and the other attached directly, both using the rear ports (which previously was hit or miss, mostly miss).
Hopefully this will resolve my random reboot issues, though I’ll have to do some video calls to know for sure.
