Payroll area is locked for master data - Does not lock all infotypes

We have released the payroll area. So when hr administrators go in to enter / edit data,

it allows to edit certain infotypes while not other infotypes. We want to lock all infotypes from been edited once the payroll area is released.

is it a infotype level setting? I tried to see in PM01 but did not find any particular setting that influenced this behavior

Appreciate any inputs rere
