I'm free at around 7PM.
Is it correct?

There is even a literary device known as prolepsis, which deals with exactly this.
How often have you heard someone in a movie or TV show say:
Reach for that gun and you're a dead man.
That is one example of prolepsis. Your example is another.
There’s an argument that “at around” is not strictly correct, as either you’re free at 7 p.m. or around 7 p.m., but not both.
But it’s certainly widely used colloquially.
It's understandable, and would probably be used by most native speakers too.
It would be more (temporally) correct if you said "I will be free at around 7PM", but I'm not sure that anyone would really pick up on the difference.
