Please add a "disable all chat"

Hey, I would very much appreciate it if you could add a "disable all chats" option that would disable pre game in game and port game chat and have maybe a deafen icon next to you to show it because when you mute people it's already too late they flamed and it's only in game can't shield from the toxicity of pre game or post game. Plus chat is completely useless with the right usage of pings. Edit I forgot a s in the title it's all CHATS as in multiple chats not the /all
