NIPT and gender testing

Has anyone done NIPT? Did you have to pay extra to know the gender, or is it included in the cost? We already know the gender because it’s an <a href="https://glowing.com/glow-fertility-program">IVF</a> baby, but I’m just wondering if my NIPT will be a little cheaper if we don’t ask for gender testing? I’ve also heard that some of the genetic issues they look for are gender specific, so does that mean they test for the gender no matter what you pay? Any input would be helpful. Thanks.
