How to disable USB-C charging?

I connect charger first and then screen, in this case original charger is used as power source, but when it goes to sleep, or monitor goes to sleep, then sometimes after wakeup it starts charging from LG's PD instead of original charger, this happens with both M1 Macbook Pro 13 and Intel Macbook Pro 15^ 2016 model, also I had 13^ intel one, which was totally destroyed,

I’ve received more useful answers on other resources than on official Apple forum, so sad…

I need the way to disable USB-C charging, I know there are lots of topics about that, but final answer is always, keep it, because it doesn't heart battery to have constantly plugged in... I know it doesn't, I don't mind if charger is connected all the time, but I don't want other devices to start charging my laptop.

*** I have 4K LG screen, that has power output 50 WATTS and already damaged 2 Macbook Pro batteries, because it is unable to deliver enough power, so whenever I do my work 15^ model starts slowly discharging when it's CPU/GPU is needs lots of power, now I connect charger first and then screen, in this case original charger is used as power source, but when it goes to sleep, or monitor goes to sleep, then sometimes after wakeup it starts charging from LG's PD instead of original charger, this happens with both M1 Macbook Pro 13 and Intel Macbook Pro 15^ 2016 model, also I had 13^ intel one, which was totally destroyed, I had to take it to repair service, because of this and replace some chip on board other than just battery, so please if anyone has any solution I'll be very thankful.

*** Display also supports HDMI, but it supports only 1440p 60hz over HDMI(it has HDMI 1.1 or something), If I want to have 4K 60Hz I have to use USB-C, we have 4 screens same model at office and it damaged several macs already,

so if you have any suggestion, it would help us a lot, I don't want to damage more Macs especially new M1 because of this USB-C problem, I can't find proper C to C cable that supports only display output either.

thank you.

You do not have to micro-manage your battery charging—

the computer will not over charge and manage the appropriate power input.

You are not going to disable USBC charging... this is the preferred...

I'd think the solution to your problem is to use the proper Apple charger and no other. Apparently your setup is not electrically compatible with Apple's electronics.

Use the Apple supplied charger. It does not matter if your display also provides power.

You do not need to micro manage the computer charging system. The MacOS handles that very well. You are going down the wrong path in your troubleshooting effort. But you prefer to insult those offering you advice rather than maybe take what you are told as possible being valid suggestions.. Best of luck in your efforts.
