It is not the cable modem itself that is bufferbloated. It is the head end
working with the cable modem. Docsis 3 has mechanisms to avoid queue buildup
but they are turned on by the head end.
I don't know for sure but I believe that the modem itself cannot measure or
control the queueing in the system to minimize latency.
You can use codel or whatever if you bound you traffic upward and stifle
traffic downward. But that doesn't deal with the queueing in the link away from
your home.
