If the entity of enum A is different from the one that you are showing in the page you could do one of the following:

1. Put the entity of enum A in the page as well, this way you could set the conditional visibilty with enum A for enum B. Something like this:


2. You could use the 'show by condition' widget from the appstore. This allows you to show the enum dependent of the result of a microflow.
