Splitter/amplifier question

I currently have xfinity gigabit internet and phone service, looking to add X1 tv service. Between the ground block cable and the coax entering the house there is a POE filter with a sticker that says Do Not Remove, needed for DVR service. My 2 questions are (1) if I add a Commscope amplifier/splitter outside, to split the incoming signal between internet/phone and tv, does the new amplifier/splitter need to have a MoCA filter (model CSMAPDU9VP), or is the non-MoCA model (CSAPDU9VP) sufficient because there is already a POE filter outside? and (2) if I get the MoCA model, do I still keep the current POE filter attached outside?
