According to documentation (
Refinement with minimization (selected part of model):
% phenix.refine data.hkl model.pdb strategy=individual_sites \
This will refine the coordinates of atoms in chain A only.
In your case selection would look more like sites.individual='not (chain A
and resid 123)' given you want to exclude residue with number 123 in chain
In GUI (latest version), go to "Refinement settings" tab, button "Select
Atoms", "Refinement Strategy" tab and put the selection there.
Hope this helps,
