It appears there is a new revision for 3-color 2.9'' Epaper Module:
It gave extra bridges for configuration (similar to 4-lines SPI/3-lines SPI selectors), labeled SB3, SB4, SB5, with SB4 and SB5 populated with 0 Ohm resistors. Also one of SMD components is not soldered.
What is this version? Does it still uses SSD1680 controller?
It seems to be compatible in 4-pin SPI, but I can't make it react to command in 3-pin mode (although it can be as well an issue with my SPI code).
