It's possible by creating a timer which calls every second or half second a callback which checks if any player is in this area or not.

First we need the timer in OnGameModeInit or OnFilterScriptInit

pawn Код:

//...
SetTimer("SlowUpdate", 500, true);
//...

then this

pawn Код:

new bool:isInAtm[MAX_PLAYERS];
forward SlowUpdate();
public SlowUpdate()
{
    for(new playerid = 0; playerid < MAX_PLAYERS; playerid++)
    {
        if(!IsPlayerConnected(playerid)) continue;
        if(IsPlayerInRangeOfPoint(playerid, 2.0, 2166.80, 1905.00, 10.72))
        {
            if(!isInAtm[playerid])
            {
                isInAtm[playerid] = true;
                ShowPlayerDialog(playerid, DIALOG_BANKMAIN, DIALOG_STYLE_LIST, "{FFFF00}Bank Account", "Create Bank Account\nLogin Bank Account", "Select", "Cancel");
            }
        }
        else if(isInAtm[playerid]) isInAtm[playerid] = false;
    }
}
