Hello,
Your question is not related to some VMware technology but to the methods provided by the guest operating system manufacturer.
In your case it is documented here: https://learn.microsoft.com/en-us/windows-server/storage/disk-management/extend-a-basic-volume
You basically have to use a tool, there are several, to "move" that 520 MByte partition currently in between to the end of the disk.
As usual, it's best to have a backup in case things don't go your way.
Regards,
Ferdinando
