Does this 16GB RAM require XMP?

The G.SKILL Ripjaws Series 16GB DDR4 Laptop Memory can run at its rated speeds out of the box without the need for XMP support.

does it work with acer nitro 5 (i5 10300H one)?

I think they just run at 2733. Check what it comes with using cpu-z or open it up and look at the label to be sure though.
