Ok, so after researching a bit more here's what i found.
First we'll still include the reply above as the solution for not show the keyboard installed there. (it will be up to you guys if you want to enable it).
Now, a fix for how to disable the ctrl + shift keyboard switch.
I'm using Windows 10 Version 20H2
Settings > Devices > Typing > Scroll down > Advanced Keyboard Settings > Input language hot keys
Now on the action Between Input language select it and Change key sequence
There's 2 options:
- Switch input Language
- Switch keyboard layout
All you have to do is Not assign the keyboard layout key. And save.
What will happen?
If your input language has more keyboards layouts, then you wont be able to switch with the key combo (you can however change to other key combo that shows there, or you can also change it manually on the bottom right)
This wont affect the default switch input language, so if you have multiple languages with them own keyboards, you're fine (unless you have keybinds that uses alt + shift at same time, then you should also disable that one too.
If you only have/use 1 input language/keyboard, disabling them wont affect anything on you, just keep in mind that if you need it in the future, you'll need to reactivate it again.
