Absolutely. Back around 15-25 years ago when information was limited (there's a heap of it around now although sometimes I almost wonder if a lot of BS is better than nothing at all!) I was experimenting to see what would work. With skinks and dragons, UV made no difference but the supplements made the difference between terrible results and thriving, perfect lizards. UV just made no difference.
I've kept plenty of small monitors with and without UV long term, and again, it just made no difference at all, they absolutely thrive without it. With the monitors I've been able to have good results without supplements as long as the diet is highly varied and nutritious, but it's much easier just to give them crickets/woodies with supplements, which for me always worked just as well as anything else. For a while I kept some on a diet of wild caught small fish, stick insects, beetles and other wild insects, eggs, occasional turkey mince, a few captive bred insects and all sorts of other stuff. The lizards thrived but there was no benefit over the much easier diet.
I have actually never, even once, seen anything empirical to convince me that UV is worth bothering with, for any herp. Perhaps in some cases it is beneficial or necessary, but I'm yet to see it. There are plenty of claims and articles about the benefits or necessity of UV, but all the real world experience I have tells a very different story.
Most of the people who say UV is necessary because they use it and get great results have never tried keeping without UV, so they don't know. "My lizard gets UV and is healthy so they need UV" is a common story, but it's like saying "I wear a tinfoil hat and have not been abducted by aliens".
