Is there any way to actively log into Steam more than 5 times concurrently?

Yeah, that title might sound a little nuts to most of you. So I host LAN parties at my home, have a number of PCs and even some PCs setup for guests who can't bring their own PC. I also have LANCache running on my network with a 10gbps link, which acts as a cacheing proxy for Steam downloads and more. After replacing some switches I set out to stress test the setup and the LANCache by logging into Steam on every PC, laptop, and even the Steam Deck, have them all download Counter-Strike 2 at the same time and basically slam the network and the LANCache. ...Then my logins started bumping other devices off or refusing to log in themselves. It seems that Steam won't let you have more than 5 clients actively connected to Steam.

Is there any known way to bypass this limit, other than creating a additional Steam Accounts since CS2 is free?
