There is an option that can be placed into the UserJavaScript.js file to disable the ability for user clicking on read-only fields. This has the effect of making them read-only on add and edit screens.
To accomplish this, create an array of the field names that should be rendered in this way. The assumption is that the values in these fields are already rendered as toggle boxes. The name of the array you create is evUserCustomReadOnlyFields.
For example, within the UserJavaScript.js file, use this statement to apply the conditioning to fields named TEST_PLAN_COMPLETE, NEED_DOCUMENT:
var evUserCustomReadOnlyFields = ['test_plan_complete', 'need_document'];
