A question on enrollment of these. Do you have these as a DEP PreStage that defines the passcode setting, or do you have a secondary profile that does that?
The target would be to exclude these devices from that current policy because the system always goes for the most restrictive policy if 2 exist. It may mean re-enrollment.
As far as the screen lock, the Passcode section of the Configuration Profiles has a drop-down for timing, but without a "Never" option, I'm unsure if just leaving it alone would achieve that. I assume it would default to whatever factory settings the iPads ships with on time.
