I had to do some research on my own about the differences between static and dynamic LACP.

I see no indication that dynamic LACP will not work with Firewall Enterprise, the warning only seems to indicate that a misconfiguration of the switch along with the use of dynamic LACP could possibly cause a loop.
In fact, I have LACP with 10g links setup in my lab right now and I am fairly certain that it is dynamic LACP as the ports in the group communicate with each other in order to determine if they are up or not.
Hope this helps.
