how to change chain line?

[urastus]

I have a merida e140 - for all intents and purposes the same as a 2020 e160 (e8000). I'd like to move the chainline in toward the motor 2mm or so - is this possible? I imagine a different spider or something. I predominantly use the first 9 gears (out of 12) and also running non shimano chain ring.
