But is it possible to always boot on the ssd (second boot choice), and only boot on network (first boot choice) if the boot "service" is available on the network (manually activated, if a problem occurs again)?
In theory, yes.
Set the boot order in the EEPROM so that network is first, then NVMe. Check the official documentation for how to change boot order.
Beyond that you may be able to do something with conditional filters in the EEPROM config or config.txt but using those might involve physical access to set a GPIO state. There's also reboot n where n is a partition number - It may be possible to force network boot using that and a separate boot partition.
