simple answer is "No" unless the hvac unit is replaced.
The 4 zone has 3 types. T8 models, T5 and T6 and xc90.
T8 (sedans) do not have center rear console vent out but sides and under seat vent outs are controlled independently.
T5 and T6 (sedans) have have center rear console vent out, sides and under seat vent outs are all controlled independently.
XC90 similar to T5 and T6 sedans plus they have additional blower motor for the third row seat.
In order to completed the retrofit,
each vent out has its own temp sensor. needed to be added and wired to the CCM. (under seat and center console or side (T8 sedan) )
In order to control the rear temp and air flow 4 missing actuators should be added and wired to the CCM.
You can find a used complete 4 zone HVAC and add the center too but it's very expensive job. I would consider retrofitting it only if I ever need to replace the HVAC unit because of of a leakage or something like that.
