Grammarly says this is sentence fragments. Is this sentence OK?
Beneath his gentle demeanor was a fearless and forthright man who was not afraid to defend his work or his faith.
The sentence isn't in passive voice, but the structure is complicated. You have a prepositional phrase, Beneath his gentle demeanor, serving as the subject. A prepositional phrase can serve as a nominative, and it even makes some sense here as the subject, but you're stretching things.
Let's change a couple of things, get back to a standard construct, and see what it looks like.
Beneath his gentle demeanor, he was a fearless and forthright man who was not afraid to defend his work or his faith.
By adding 'he' as the subject, we conform to standard grammar. We need the comma after the introductory phrase, but none is necessary in the rest of the sentence.

The way I parse this, it's in passive voice, but not a fragment. If it was in active voice, it would be "A fearless and forthright man, who was not afraid to defend his work, laid hidden beneath his gentle demeanor." I prefer the passive voice here.
