Hi, I assume the planarity you mentioned is what is discussed in Moriarty et al (2020) https://doi.org/10.1107/S2059798320013534
As shown there, it is known to have some deviation. In Refmac (or in the CCP4 monomer library) it is restrained using a torsion angle with 5 degree sigma instead of the planarity restraint. You can tighten the restraint using an even smaller sigma. The keyword could be: restr tors include resi ARG name chi5 sigma 2.0 By the way, did you mean by "outliers" those from the PDB validation report? I have had a feeling that their criterion is a bit too strict. Could anyone from the PDB tell how the outlier of the ARG sidechain is calculated?
