Does AMBER include effects from pH?

I've homology modelled a protein from MODELLER.
No H atoms is included.

Then when I subject it to AMBER for MD, can I choose
what pH in that simulation?

Because under different pH, the individual AA may "feel"
different environment.

Can one tell how to calculate the ionization state for each residue
under different pH?
