How do I keep my DPF working properly?

I have a 2022 Dacia Duster Blue dCi. I was told to take it for a motorway run at least one a month. I only do 8500 miles per annum but half of that is motorway. Is 1700rpm @ 60mph fast enough to keep the dpf clear?

The ideal run on a motorway/dual carriageway is to have the engine at 2000 rpm for a minimum of 25 minutes.
