Method 1:
Detour GetConVarNumber to exclude sv_cheats and sv_allowcslua.
Method 2 (best):
Prevent the file from running. (RunString hook)
Method 3:
Destroy the "lorza_anti_cheats" timer.
EDIT:
Holy shit, the actual ConVars are clientside and not replicated...
Just set lorza_AntiHacks to 0 in your game console.
There are more methods to bypass this pile of shit though.
Have fun.
