Unless self install FTTC has been rolled out, then the answer is no.
The HH5 is meant to be able to be used without the white Openreach modem, but until that option appears you are stuck with the usual white Openreach modem, and the usual master socket, or data extension solutions.
FTTC is a LOT more sensitive to the in home wiring, so sorting that out into the most optimal solution is a very good idea, and generally the way FTTC is installed by the engineers means this happens.
