“Are there any non prescription hydrolyzed protein dog foods on the market”?
NO, there are not, and mixing in another food defeats the purpose. Stop adding stuff to the prescription food.
Offer a meal 2 times per day, your dog will eat when he is hungry. He will be fine as long as he is drinking water (have fresh water available 24/7)
If he goes 72 hours without eating solid food then call your vet and discuss diet options.

Veterinary prescription hydrolyzed protein dog foods are an excellent choice for both food allergies and IBD. These diets are manufactured under the strictest quality control measures, which ensures that they arenāt contaminated by ingredients that are not included in the label. Eating prohibited foods is a major reason that diagnostic food trials and treatment for food allergies and IBD fail.
