Create Custom Entries to Hide Preboot and Recovery APFS Volumes with Clover Configurator
With the release of High Sierra and the APFS file system, Clover users now have "extra" entries appearing in their Main Menu - Preboot and Recovery APFS volumes. While they are harmless and actually useful in certain circumstances (eg need Preboot to boot if using File Vault encryption, need Recovery to fix some file system problems), most users will likely want to hide them in day to day use.
OK everyone, here's an answer to myself that I post for everyone else to see.
Custom entries is quite tricky and very little documented. So here's the easy approach that I took after 50 like, reboots
Main Clover settings:
<key>Scan</key>
<dict>
<key>Tool</key>
<true/>
<key>Entries</key>
<true/>
<key>Legacy</key>
<false/>
<key>Linux</key>
<false/>
