Does deadline support single frame Tile rendering for vray GPU?

Hello,
my software: 3ds max 2018 + vray 5.05 + deadline v10.0.25.2
I render one frame by using vray GPU, seems the frame is not splited to regions, the whole frame is rendered in every slave node!
if change to vray CPU, it works well.
So, it is deadline’s feature issue or the vray’s ? thanks a lot!
