Different keyboard layouts in different applications (Windows)?

Question

Keyboard layout

The essence is banal - 3 languages, the third is used only in one application. And so there are Ukrainian and Russian - between them you see the difference when only when you stumble upon Y (I), E (Є), etc. The question is purely convenience - switching layouts is not difficult.
Is there a utility that will allow you to cut out a certain language in all applications, leaving it in only one? Just so I can't even switch to it.
About programs that shine language tips near the text pointer - I know, but alas, they do not work correctly in the same Firefox.

Answer 1

A partial solution was found thanks to Moskus & SOTVM - through the Punto Switcher utility.
An example of program settings
That is, the essence is to assign the switch "eng-ru" to one combination, and "eng-ru-ukr" (my case) to another.

Another solution. Essence - on клавиша + ы => i; клавиша + shift + ы => Іand so on. Set AutoHotKey for key remapping. Create a script (RMB in any folder - create - AutoHotKey Script).
Script code example

!+S::Send {ASC 0178} ; alt + shift + S (Ы, для русской раскладки) = І. Ремаппинг заглавных должен быть перед строчными!
!s::Send {ASC 0179} ; alt + s (ы, для русской раскладки) = і
!+'::Send {ASC 0170} ; alt + shift + ' (Э, для русской раскладки) = Є
!'::Send {ASC 0186} ; alt + ' (э, для русской раскладки) = є

Answer 2

Is there a program to automatically change the keyboard layout when the programs focus?
