That doesn't need to be clipped lol unless there is some dead undergrowth I'm missing. In that case you can clip off dead shit whenever you want lol or it'll just fall off eventually. Looks a little droopy. Either overwatered or you just watered before the pic was taken and it hasn't picked back up yet. But it looks good to me overall. I can see your new growth beginning to branch out. I would just leave it alone it will fill out some more.
