I could use the VPI instead of the desicant chips I'm using now but aren't desicant chips treated with VPI? I could be wrong but I think they are.

Dessicants are moisture absorbing materials. It is possible that some chips might be treated with VPI, but I sort of doubt it. Dessicants can easily be recycled by heating to dry them, restoring their capacity to absorb moisture. The VPI property would not survive the heating.
