That's what I wrote.
If the OLED connections on the flex cable are the same as those on modules with the solder selections, TS could figure out the pins on the flex cable that need pull-up/down to select i2c and solder wires to make that selection. In all selectable modules it's only two or three connections. Of course that requires more effort than just buying a different module - and as I wrote he would have to feel adventurous (and have some fine soldering skills)...
