I just bought a new 2023 Ram Cummins 2500 so my question is. If I put a fuel filter & water separator bypass on my truck will it void my warranty? If it doesn't, what would be the best bypass and filters to use?

Why would you feel the need to add a 3rd fuel filter to your truck being the fuel filter under the hood ( its your second filter in the fuel system) removes/separate water out of your fuel?

Any modification to the fuel system will give the dealer a reason to make any warranty claims your pocketbooks problem.
The fuel system is already stout with dual filters, no need to run a third filter unless you run questionable fuel sources.
There are kits available to change the rear filter assembly to one that uses a CAT spin on filter. Probably best to find one that retains the water in fuel sensor and fuel heater.

I wonder why one would want to bypass the water separator on a new truck? Water in a diesel engine usually results in a very bad day. Stellantis will most assuredly void the engine warranty if the stock water separator has been bypassed. IMHO, rightfully so.
