I have a Mac Mini for personal use and a Macbook for work. Both are connected to a splitter, so I can use the same monitor whether I’m on the Mac Mini or Macbook. However, because of how close both computers are, the Macbook will want to connect with the Mac Mini, which I’m wanting to avoid to keep work separate from personal stuff. I’m not sure what this is called, but how do I disable it?
MacBook Pro 13″, macOS 14.5
It wouldn't be Sidecar between two Macs.
If you see one of the Macs offering to let you use the other Mac as a display, that would suggest that you are looking at AirPlay, and that the Mac that is showing up as a possible AirPlay destination is set up as an AirPlay Receiver for AirPlay to Mac.

It doesn't mean that the Macs are mixing personal and work data, or that you even need to make the AirPlay connection (which will just let one Mac take over the other's screen.).

I'm not sure which feature you're talking about. You could look over this list and see if there are any that appear to match the specific behavior you are seeing.
