If a person eats 0 vegetables for a long enough time will they lose the digestive enzymes for vegetables? If not then why?

Well we don't really have many digestive enzymes for vegetables. Vegetables which get broken down to cellulose which are  β-linked D glucose chains contain a lot of "potential" energy. We do not have the enzymes necessary to break those bonds and extract any glucose.
Your body, however, will generally produce less of an enzyme if it is not being utilized as it exhibits and unnecessary metabolic cost.
