user57608: which flash option do I need to take to use EEPROM?
Can I flash with 1MB and no SPIFFs and still write data to EEPROM?
thanks T

Yes. The EEPROM emulation is saved into different part of the flash, not to SPIFFS.

which flash option do I need to take to use EEPROM?

There is no special option in Tools menu for EEPROM emulation. Only use the library.
