Thank you for your advice, if I want to constrain the dihedral CB--CG--CD--NE of Arg residue. Do I need to define a new bond ? would you give me more details about the technique . I am a fresh man in this field, I really need someone to give me more details.

You could alter the parameter file, setting a high force constant for
the desired dihedral. In the likely case that this would affect other
dihedrals that you don't want to constrain, you would have define new
some new atom types.
