The short answer is no.
The longer answer is that anywhere on planet earth where there is water, you certainly can "shore dive". It doesn't mean you'll see anything.
I've been visiting or living in the Keys for a few decades, and I've "shore dived" because it was hot and I wanted to get wet and get some swimming exercise. However, there is little to see.
I had a place at MM103.5 for a few years and used to ride my bike down to Pennekamp in the afternoons for a fitness snorkel. Didn't see much but had fun anyway...approached by manatees! If you get in 1-2' of water around the mangroves, the macro life is quite fascinating.
Still...the "shore diving" in the Keys gets old fast.
Yes, you can take a small boat out to the shallow reefs but be careful, check the weather.
I'm envious that you got a job and are moving down there, if I could get a nice gig with housing, I'd be down there in a minute myself!
Enjoy!
