I have been searching for a while and now finally I found a way to enable Enhanced Processing on every Mid-Range.
Requirements:
•Secure Folder
•CCSWE App Manager APK 5.0.0
•Splashtop Add-on (Knox) to enable Knox licence
•And some patience.
-Install Splashtop Add-on from link below.
https://play.google.com/store/apps/details?id=com.splashtop.streamer.addon.knox
-Open and grant all permission required.
-Create Secure Folder empty
-Add Splashtop there and grant all permission again.
-Uninstall main Splashtop first and then all Secure Folder (at Secure Folder settings)
-Install CCSWE App Manager 5.0.0 and grant Knox Licence

-Wait some minutes and open app.
-Search for Device Care and go to Services
-Find at Services Enhanced Processing
-Enable and check Quick Panel!
Splashtop device admin 
Install CCSWE after uninstalling Splashtop and Secure Folder Data. 
Enable Enhanced Processing at the Services.

Do not uninstall CCSWE! You need to enable Enhanced Processing activity again!
