It really depends what server you're playing. For HCF if its Viper Autoclicker 8-13CPS, Reach 3.00 - 3.04, Velocity 90 100 100. These are just closet cheating settings so you could probably go a bit higher if you wanted to.
First go over here to settings : https://gyazo.com/5009f749f86f5caa61568b5555181acb
next when you are into settings scroll down to "Debug Settings" and select "Launch Minecraft in Debug Mode"

There isn't really a point for self destruct on v4 since it cant bypass screenshares. Even if there was a self destruct the client would be found pretty easily.
