Thanks for posting in our communities. Your thread as been moved to Intel® Optane™ Memory support.
Once you enable Intel Optane memory, both Intel Optane memory and the accelerated SATA drive appear as one SSD volume to the operating system. As a result, the options for defrag aren't available.
You can find more information about Intel Optane memory features and requirements here:
EDIT: Just for you to know, defrag is not available since it is not required. The Intel® Rapid Storage Driver (used by Intel Optane Memory) takes charge of maintenance and garbage collection functions on the accelerated drive.
