How you can setup solo mining Antminer S9j utilizing cgminer from Mac OS

I’ve a Mac Mini M1 which has put in cgminer 4.11.1 from github repo and runs Gekko miners fairly effectively through USB connection utilizing my native bitcoind node. I now even have an Antminer S9j (which has an ethernet connection, no usb), however I do not understand how I can join it to the cgminer.

1. Ought to I join the Antminer to my router, discover its IP, and in some way (how?) specify to cgminer this tackle so it could actually discover it
2. Ought to I join the Antminer to my Mac Mini through a usb adapter and in some way cgminer would discover it? (It finds the Gekko miners robotically)
3. ??

I’m additionally undecided whether or not I must rebuild my cgminer with some related --enable-?? flag, ex --enable-bitmain which btw has linker errors, to ensure that cgminer to have the ability to talk to the Antminer? Or is there a regular protocol by which cgminer is ready to talk with an ethernet succesful miner, ex stratum?
