How to block keyboard keys which are using in vjoy

i am really having a bad problem with vjoy ..its tht when i set any key in vjoy..and i open the game eg ( divinity oringal sins ) it ask for press a keyboard/ a controller ...at this situation to play coop mode in it i need to press a controller button ...but when i press keyboard key which is set to vjoy ..then the game switch to keyboard mode..because any key assigned to vjoy it first goes as keyboard key then after some sec it goes as a controller

Can u guys add a block key option in it?
Headsoft vjoy have a block key option but mapping in it is very hard
