XB6 Modem and MOCA filters

I want to move my XB6 modem (internet only service) to the garage where my Arris Gateway TV Box was and I have a mixture of "regular" outlets and MOCA filtered outlets in my house because I used to have a mixed Gateway/DCX setup. Am I right that the XB6 needs to be on an outlet with a MOCA filter (which the old Gateway outlet will be)? I have a 2nd choice location which is an outlet w/o MOCA filtering.
