Not really specific enough on the GPU, but likely not directly with an off the shelf adapter. Unless the GPU came with a DVI-VGA adapter it isn't likely to support the straight through adapters that are inexpensive.
DP to VGA would require an active adapter, which is kind of expensive.
Not too much call for VGA these days. HDMI has been the consumer standard for quite a number of years. DVI itself is pretty legacy and Display Port is the cutting edge for professional graphics (Thunderbolt and USB 3.1 aside)
