What files from Commerce should be enabled/disabled on a Content Delivery server.
I can see all files from folder : App_Config\Include\Y.Commerce.Engine use a rule-based configuration like :
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/"> <sitecore role:require="Standalone or ContentDelivery or ContentManagement">
But the file from \App_Config\Include\Z.Commerce.Engine\ doesn't contain rule based configuration.
Also the files from Include folder doesn't contain rules based configuration.
