Should be able to.

The optional 220A alternator is:
KW5 Alternator, 220 amps

Some on lots 'here' have that option added.

And factory dual alternators is:
KHB Alternators, dual, 150 amps and 220 amps each

They gotta have parts available for service and/or crash usage.

(duals are only available with the duramax)
