Close all instances of Adobe Acrobat on all target machines before proceeding.
Locate the FeatureLockDown folder in the Acrobat installation directory (typically under C:\Program Files (x86)\Adobe\Acrobat <version>\Acrobat\FeatureLockDown).
Open the FeatureLockDown file (FeatureLockDown.json or FeatureLockDown registry key, depending on deployment method) with administrator privileges.
CautionEditing FeatureLockDown requires administrator rights and affects all users on the machine.
Add or modify the relevant accessibility-related settings (such as disabling user modification of accessibility options) according to Adobe's documented FeatureLockDown keys for accessibility.
Best practiceRefer to Adobe's official FeatureLockDown documentation for the exact key names and values for accessibility controls.
Save the changes to the FeatureLockDown file or registry and ensure file permissions prevent standard users from editing it.
Distribute the updated FeatureLockDown configuration to all target machines using your organization's preferred deployment tool (e.g., Group Policy, SCCM, or manual copy).
Restart Adobe Acrobat on target machines to apply the locked accessibility settings.

If you just set the settings once, users can still change them later. Locking them with an admin policy means users cannot change those options at all unless the admin unlocks them.
Schools and businesses might want to lock these settings to make sure everyone has the same experience, to meet legal requirements, or to stop accidental changes that could make documents harder to use for some people.
