I work with McAfee encrypted drives, the only way I found to delete is:

* From a WinPE enviorement, run CMD and type:

diskpart
list disk    (lists the disks)
select disk 0    (0 being the disk to setup)
clean    (wipes the disk)
create partition primary (creates windows partition)
select partition 1
format quick fs=NTFS (Format primary partition)
assign letter C
exit

or

* Boot the Pc with the encrypted disk from a Windows 10 installer USB, when prompted to select the target disk, delete all partitions from the encrypted drive and create a new one.

or

* Boot the pc with the encrypted disk from a Live USB Linux distro, use Gparted, delete al partitions and create a new one.

If you're working with McAfee encryption over a Kingston SSD, try upgrading the SSD firmware, you may "magically" decrypt it
