Pool beam and coping stones too high can I cut...

I am going for the more modern look. If I can't then I'll just resurface the chattahoochie deck with stone or something. Thanks!

Your photo is not detailed enough (probably need close-ups, including one from the pool side of the coping) to reveal whether that's laid coping (non-structural) or poured coping (structural).

That's a key point, that needs to be resolved before others offer advice.
