I recognise those boot ‘errors’ but they don’t stop my FW 13 AMD 7040-series from working with my 40gbps Thunderbolt 3 cables.

You might also need to check the release thread for the 3.18 BIOS on Framework 13 AMD 7040-series – a number of people are having isues with peripherals on USB4 docks at boot. It’s why I’ve not updated beyond BIOS 3.17, you might want to roll back to 3.17.
