Simple way:
csgo/scripts/vscripts/warmup/warmup_teleport.nut

function OnPostSpawn()
{
	...
	if (GAMEMODE == 1 && GAMETYPE == 0)		// check if we're running comp
	{
		COMPMATCH = true;
	}
	...
}

We can just set:

COMPMATCH = false;

That will disable 1v1 arena in competitive mode.
I guess we could make arena work on other modes by modify this file.
Edit this file works after mp_restartgame/map change.
I've never seen any command ingame can switch arena.

So I think need plugins that can hook some entity using this Entity Script if we want use command switch ingame.

Interestingly, would anyone create a plugin to do this?

I believe that whenever you update the game it will be replaced, correct?

I had seen some files will replaced when game update,but some not.
I guess it's depending on those files have new release?
