If you don't mind delving into a bit of home automation, what I would do is to use something like this:
1. Some kind of smart AC control unit for each AC. Whether it's a smart thermostat, or something like a Sensibo that uses infrared signals to control the AC.
2. A smart home hub. As Madcodger mentioned, Hubitat is one option. I personally prefer Home Assistant (I'm experienced in both).
With those in place, and a bit of learning, you can program just about anything you want. It would be fairly simple to prevent more than 2 ACs to run at the same time. Or, if they're inverter types ACs, instead of outright disallowing 3 units to run simultaneously, you could say that if a 3rd unit is switched on, you can still allow all 3 ACs to run, but override their set points automatically so that the power draw from each AC will be lower, and therefor lowering the combined power draw.
