GPU TGP and Overclocking

[HERSR]

Hi. I have a Zephyrus M16 2022, 12900H 3080Ti laptop with vBios from Zephyrus duo 3080ti flashed in. On the DUO the gpu runs max 155 watts on turbo mode and so can mine. But on the duo it will gets up to 165w in manual mode and mine remains 155 watts in manual mode, with dynamic boost scroller at max. I guess the power plans (perf/turbo e.g.) is blinded with cTGP mode 2 (if I call it correctly). Is it possible to get that 10 extra wattage by any means? Any opinions are welcomed.

Also although the upper limit of GPU offsets are improved, it’s still limited by vBios. It has the maximum video mem offset of +300mhz as I see in afterburner. I dragged to 500 in g-helper and it just jumps back :(
