Left 4 Dead 2

All 8 Survivors Sourcemod 2018-2025 [Stable DHOOKS 1.158]
Can we exceed the amount of 8 'players'?
I know how to change the number of survivors in l4d_superversus.cfg. Is there any way I can add more than 8 players in the game? Because when I tried to change the amount of maxplayers on the console (e.g. sv_maxplayers 8), it always stays the same. Thank you in advance!
