to disable parts of the current functional forms, you simply need
to change the parameters. but to add new contributions could
easily become a non-trivial task.

you most certainly need to do programming.

there is no just one file. are you sure that you want to do this directly
with a code like NAMD? i would _strongly_ suggest to first 'practice'
with an MD code that has a simpler structure, so that you know exactly
what to change.
