I believe you can't. As far as I know, addresses are generated the same way, except for the randomness part maybe.

bitcoin core like any other wallet program is creating a "bitcoin address" and that has a clear definition. it is simply hash of a public key with a specific formatting that makes the result be a string starting with 1, 3 or bc1. it doesn't matter what the wallet program is, they all do the same encoding.

imagine it like this:
you have a number that you want to represent. you have many ways.
decimal: 255
binary: 11111111
hexadeciman: FF
Base58: 5Q
Base58 with checksum: VrZDWwe

and this last way of encoding is what the bitcoin address version 1 uses. and it is shared among all the different implementation of bitcoin protocol including bitcoin core, Armory, Electrum, blockchain.info,...
