I want to override DLM/DSLAM Interleaving/G.Inp profile for better latency

Hey everybody.

I am using a lantiq device with vdsl modem [TPLINK TD-W8970 V1]
I need any way to override DLM/DSLAM interleaving/G.INP profiles.
Any assistance will help me a lot.
My ISP is lazy and keeps ignoring my request regarding latency performance.
My line is perfect with loop length ~340Meters
Latency is more important to me than Data rate, I should be able to have 60MBITS DS and 10MBITS US without inteleaving/G.Inp !!!

Please help me achive this.
