Accelerate DPF regeneration?

Hello, is it actually possible to accelerate the regeneration process of the RPF, for example, by driving only in 5th gear – so high-touring – on the highway? Reason why I ask: My moose, or I, have already stopped the regeneration twice, because the route was too short. After the engine was switched off it was clear to smell that the RPF was in the middle of the regeneration. And unfortunately this was already 2 times in a row. Thank you. LG, Nordisk.
