Should work the option "Minimum Gang Solder Mask Web" for BGA?

Seems it doesn't work.

In my 36 year PCB design career, I have never seen a Gang Mask on a BGA. 

And I would not recommend that you do that. 

There must be Solder Mask between every BGA pad to prevent solder bridging under the package.
