Install and use different DSL driver - is it possible?

I've installed LEDE v.17.01.0 final on the TP-Link TD-W9980 and I'm wondering if it is possible to install and try a different version of VDSL driver, for example one that supports vectoring. I've seen this happening here, but the procedure isn't explained.
Is there an easy way to do this in LEDE, without building it from the beggining?

From It seems that you can add this to the config

option firmware '/path-to-firmware'

to add driver support
