That is difficult to answer without more details.

Generally, you can't see disulfide bonds in CG systems without first converting them back to an all-atom structure file.

If you want to see how the structure changed of the protein after adding disulfide bonds then this is relatively easy with CG, but it depends on what you're simulating and expect to happen. Generally, we use CG for large systems that are expected to take a long time to fold or self-assemble.

However, they are imprecise for simulating hydrogen bonds and can't visualize specific atom connections.

If you are looking to simulate if a disulfide bond forms, then this is definitely the wrong method.

Thank you for your reply.

That's what you said, I want to see how the protein structure changed of the protein after adding disulfide bonds. Can you provide reference?

CG simulation makes multiple atoms(including two sulfur atoms of disulfide bonds) into a single bead, atomic information is lost.
