Handling Esports traffic at a college

So the college I work at recently added an Esports division. We've been having major problems with packet loss and recently we got a new phone system that uses sip, and Overwatch voice chat is being seen as SIP and not going through. We have to disable ALG on the Palo Alto to make it work, which then breaks the phone system. We've reached out to Palo Alto and they said that setting is either one or off and can't be applied to specific VLANS or subents.

Curious if anyone here has dealt with handling an Esports team at their college before and what kind of steps they took for handling it. The coach is already discussing getting a second internet for them which would solve their problems, but not exactly the route I want to take just yet.

Thanks!
