Resize existing partition on Drobo 5N?

I have a Drobo 5N with a Time Capsule partition of about 2Tb, and a main data partition of about 10Tb. The main drive is about 70% full. I have decided that I no longer want to use it for Time Machine backups, and want to free up that space.

Is there a way to delete the Time Machine partition, and expand the size of the main one to fill the space, WITHOUT wiping the Drobo? I know I can do it if I take everything off the drive, and reformatting, but I’m not sure I have enough storage elsewhere to do this, and I 'd prefer not to have to do this if it can be avoided. Is the partition manager that will worth with the Drobo 5N?
