Suggest drilling a small 3/8 hole close to the pipe to see how far that down the foam shown around the pipe, then if its under 2" either keep drilling out the concrete or get a 3" core bit like this https://www.amazon.com/Drilax-Diamond-Concrete-Masonry-inches/dp/B07L2H1PLF
You would need to cut the drain pipe to do this, but they make deeper 3" coring bits 8" instead of 3" deep so you would not need to cut the pipe as low.
