There is quite a gulf between being rude, obnoxious and shouty (which judges will tolerate to a point) and being held in contempt of court for disruptive behaviour - the latter is quite rare and it would take something pretty awful justify it. Judges do appreciate that not everyone can be calm under pressure, and allow a bit of leeway in my experience, sop the bar is set pretty high.
You can ask the judge to step in and give a warning about contempt if it really is awful though. You don't need to refer to FPR to make this point.
But it's the judge's discretion, and there's no point you asking the judge to make him apologise. If the judge wants an apology they will certainly ask for it themselves.
If you are having a remote hearing, you could ask that he is muted while you are talking, so that he cannot interrupt, perhaps, if he continues to do this throughout the hearing.
Other than that - if it is in person then the judge will have the ability to quieten him down in person so that should be more tolerable.
Can I clarify anything further?
