In Bitcoin Core, there's no known mining related RPC or command line option that can set a dedicated address of any ASICs.
The general setup is you have to do it in each miners's configurations, and you only have to do this once in most ASICs.
But you haven't explained your setup even a bit so there's no telling on what it's capable of.
Like: which miners (
old/new ASICs model), solo mining or pool mining? Etc.
Also, this thread may be moved to the appropriate mining board (
link).
Or you can do it yourself using the "
move topic" button on the lower-left side of the screen.
