expanding dedicated VRAM in a precision 3420 sff tower

Hello. I was wondering if there was any way to expand the VRAM from the standard 128 to like 512 MB without having to do any kind of modifications? I have searched the BIOS and the OS but neither have options to expand the dedicated video memory from 128 mb to any bigger size.

I am currently running a Dell Precision 3420 SFF desktop with an Intel I5 7500 with 8GB of RAM and using the integrated graphics Intel 630 HD. I am not trying to run high end games on this machine. Was going to use it mostly as a media center PC. Just want to expand the VRAM so I can play 4K movies and some light gaming. I have a dedicated PC for gaming. This is just for my family to watch movies and so my daughter can play older educational games. Also, it was Windows 10 on it. Thanks!!
