Post-coronavirus, I'm working from home more. Should I swap my diesel to avoid DPF issues?

At the start of the year, I bought a 2018 diesel Peugeot 3008 to cater for a daily commute of 40 miles each way and regular long distance family trips - 20,000 miles per year on average. Post-Coronavirus, my company has moved firmly to long term working from home and I'm averaging 100 miles a month. Would I be better off swapping now to a smaller petrol/hybrid equivalent and swallow the cost to change, or stick with the diesel and risk mechanical issues due to low mileage?

Modern diesel engines are not really designed for 100 miles a month. The DPF alone needs 15-miles per journey to complete a regeneration cycle:

If your driving habits have changed for the foreseeable future then it may be better to change the car for a petrol or hybrid, rather than wait for the inevitable mechanical problems. The Toyota RAV4 is available with an excellent petrol hybrid system:
