Hey there! 

Modern UI is only available to use for non production environments at this time. It is a new upcoming change to Acumatica that users are more than welcome to test this before it’s full release -- but only in test environments. 

I personally love the new design structure for modern UI, especially being able to move around form elements!

For more information on configuration and use of Modern UI the following help document can be reviewed:
