In the profile configuration restrictions on Meraki, you'll want to have "Allow modification of passcode settings" checked. Once it is, on the iPad it'll be in the settings under the Touch ID & Pass code. If not set just right, the profile and restrictions will hide passcode options in the menu on the iPad. Even if you can get to the correct section, they won't even show as greyed out. You may want to look for other profile restriction options that need to be checked in addition to "Allow modification of passcode settings". OR try taking off the profile completely, set the passcode, and reapply the profile. It might just be wiped out as soon as you apply it but it's less annoying than reading every. single. restriction.
