How to switch on special bond for a particular set of bonds and angles

Hi,
Is there any way to switch off the special_bond lj 1 1 0 to a specified set of bonds and angles
defined in different set of linear molecule ?

I have set special_lj 1 1 0 in the system. I need to switch off this non-bonded interaction to another set of linear molecule where particles are connected by bonds and angles.

Any help would be appreciated.

the only way to have different special_bond settings in the same simulation in LAMMPS is by assigning different special settings to different sub-styles of pair style hybrid

via pair_modify. please see the documentation of pair_modify for details.
