That is really old firmware, older even than what my Pi 5 came with. It’s possible you downgraded the firmware at some point if the rpi-eeprom package that’s part of your OS is not updated often, which is the case with Ubuntu and I imagine also Debian. This might have happened when running the scripts provided by Argon, though there should have been a warning about downgrading.
See my possibly outdated post here on how to download an updated copy of the firmware. It looks like my link in that post points to an older version of the repository so try this link to get a copy of pieeprom-2024-06-05.bin.
