Hi,
I want to change the non-bonded parameters to modify the interaction between water molecules and protein molecules. I am using CHARMM forcefield with Tip3p water. The ffnonbonded.itp file of the forcefield has non-bonded parameters for tip3p water. Can I achieve the above by changing these parameters?

That depends on your definition of "modify," but yes, in a way, you can make changes here.

If yes, will this also change the non-bonded parameters for water - water interaction?

Yes.
