increase the dedicated memory for the graphic card

Hello all, 

I have a Dell laptop LATITUDE E5530 with 8 Gb of memory card ( two cards of 4GB ) and Intel HD 4000 as a graphic Card. 

The current dedicated memory for the graphic card is 64MB but i want to add more memory ( 516MB for exemple ) 

Could you please help me to do that ? ( i saw that this can be done from the Bios but when i checked my laptop bios i cannot find where i can update this ) 

Thanks,

Hassen
