For people with lactose intolerance, what’s and alternative to sure gel since carrot fiber is not recommended for snack sticks?

It was noted that using sure gel creates a better product than carrot fiber. Given the sure gel is a milk based product is there an alternative to sure gel that would be recommended. Also I’m only able to bring my smoker to 150 degrees. Given that bit of info what would the smoke schedule be when starting at 150 degrees.

How many ounces of carrot fiber rather than sure gel is recommended for a summer sausage recipe?
