How to disable multiplayer when launching the Minecraft?

[EvanEvan-17]

I'm trying to make my own launcher with my OWN Parental Control feature, and I'm looking on how to disable multiplayer MANUALLY when launching Minecraft (if parent choose to disable it for their child). Is it possible? Because this is help many parents who don't want their child to play multiplayer on Minecraft, but still want their child to play multiplayer on other games. Because when they change their child's Xbox Account Settings, it will disable multiplayer in MOST Xbox Games.

this option is unavailable on current version.

I'll add this feature on next version.

Is this possible? If you can, please make next version immediately. I need it. It is through Java argument?

[EvanEvan-17]

I need this feature, please make it immediately if this is possible, if not possible, then tell me, but IF POSSIBLE, ADD IT NOW! I NEED IT!

decompile latest minecraft using mcp and find argument name like "disableMultiplayer" (i can't remember exact value)

add these argument to Process.StartInfo.Argument

ex)

var proc = await launcher.CreateProcess(~~~);
proc.StartInfo.Argument += " --disableMultiplayer");
proc.Start();

note: disabling multiplayer feature is only available on latest version (1.17, 1.18, 1.19)

OK, it is now working! THANK YOU VERY MUCH for your help. And it's look like you no longer need to do something, but if you can add this feature directly, then it's good. You can add it to next version in the next week if you don't have a time in this week.
