Normally yes, but its down to whoever is financing the phone for you if advanced payments are allowed.
If using Apple's Apple Card installments or Apple's iPhone Payments yes, you can pay more than the monthly due every month.
If financing through a carrier, you would need to ask them if they accept advanced payments.
