I don't really understand why you would do that. Can you give some
details about the problem you are studying?

ESPResSo distinguishes between DPD thermostat and DPD interaction (the
conservative part).
The DPD thermostat is always local as it couples to pairs of particles.
The DPD interaction needs to be enabled separately using hat
interaction ("inter hat").

ESPResSo has two implementations of the DPD thermostat.
1.) standard DPD thermostat ("thermostat dpd") with one friction
constant for the whole system.
2.) interaction-based DPD thermostat ("thermostat inter_dpd") where
the friction constants can be set on a per-pair basis using the
inter_dpd interaction ("inter inter_dpd").
