About the pressure calculation in lammps simulation

Is there any way in which I can exclude one group from the pressure contribution in a simulation? This group is basically a framework of atoms and physically won’t contribute to the pressure of the system, but while simulating the framework is contributing to the pressure (a constant value).
Really it’s not that big a deal as I can offset the pressure created by the framework by subtracting the constant pressure due to framework atoms, but while showing the results, it seems a bit unrealistic!

You can exclude the interactions of those atoms with themselves (and only that is the part that is constant) through creating a group and then using neigh_modify exclude.
