Preferred monetary gifts not through registry

We would prefer cash gifts for our wedding as we already live together and don’t need much. We are including a few gifts on the registry for people who prefer giving an actual gift. For cash funds, the wedding website source we are using (Zola) takes a fee for credit card gifts made through the site. Anyone word it on their website in a way that states you’d prefer cash gifts at the wedding versus the website to avoid the fees?
