You can swith on/off the part where we can win with beacons on pedestal while creating the server. but to win a game, Destroying the base is a MUST.

So there are no servers in which the game can only be won using a beacon.

but even in the future, if such servers do come out, then we can make the comm centre and temple of nod undestructible or we can make it such that if the team destroys the opponent's temple or comm centre, the team will win
