TDA4VH-Q1: Ports (balls) as GPIO

Part Number: TDA4VH-Q1

Tool/software:

I'm working on a project using TDA4VH-Q1

all ports assigned as GPIO are used (MUX Mode 7)

as I need 2 extra GPIOs (outputs) to control a MUX (TS3A27518EIPWRQ1)

some of the few ports available are 

AU8, AV3, AV4, AV9, AR5, AR6 those ports do not have information on MUX Mode column

then the question is; can some of these ports be assigned as GPIO even if there is no info on "MUX Mode" column on data sheet
