Arria V 10GBase-R lane polarity inversion

What is the setting to invert the lane polarity of one tx lane coming out of Arria V GT device. I am running 10GbaseR Phy. It used to be pretty straightforward in Arria II and Stratix IV. But I am not sure if this is even possible in Arria Vs.

Thank you for the help.

Best regards,

Sanjay
