This isn't a perfect solution, but I recently added an option to
change the weight on selected geometry restraints:
atom_selection = chain A and resseq 1000 and name MG
scale = 0.0
apply_to = *bond
The intended purpose was actually to increase the geometry weight on
problematic regions of the structure, but the reverse should be
possible. Note however that this will effectively cancel out *all*
bond restraints for the selection, not a specific linkage.
