In the 'for certain aircraft' situation, add or modify this
line in the aircraft.cfg file under:

[GeneralEngineData]
max_contrail_temperature=-24

Change the temperature to -45 or -50

I'm not sure what the minimum temperature limit is
so you'll just have to try various settings.

You could also try removing the "contrail=" statements
in the aircraft.cfg folders in the [effects] section.

To remove contrails altogether, you would have to remove
or rename all the contrail "fx" files in the FSX Effects
folder.
fx_contrail_l.fx
for instance or another is
fx_A_I_contrail.fx
