I just did some more research and aparently my intel was a bit outdatet (from arount 2020). The guide should still work, though booting from SSD should be working by default and does not require any eeprom-updates. So you can probably start with step 4.

Raspberry Pi4? Then yes, here’s a guide to update your bootloader:
