How to create a Windows uefi disk only with Deployment Solution Partiton Disk Task?

Is it possible to create a uefi disk for Windows 7/8/10 with only a Create Partition Disk Task?

When i choose GPT, the size option is grayed out??!!

Are there number of consecutive create partion disk tasks necessary?

Does somebody have a configuration sample?
