Enable pins of AD7626

I want to use AD7626 in external reference mode (+4.096V). So I need to connect EN1 to 1 and EN0 to 0.

Page 17 of the datasheet shows that pull-up of pull-down resistors are to be connected to control EN0 and EN1 during power-up. It also shows that the pull-up is VIO.

I want to know whether the pull-up/pull-downs are necessary.

Can I directly connect EN1 to VIO and EN0 to AGND.
