I think writing code with autocomplete is forbidden in contests and also while practicing, so I think it would be better to remove it.
It's not auto complete it's auto suggestions which you get while typing in an editor and it's totally allowed, they just give you syntax and keyword suggestions not the ones which copilot gives. If you don't want to use that as well, you can go to editor settings and disable it :)
