Different input source (language layout) on external Magic Keyboard than MacBook's integrated keyboard

Hi!

Do anyone know a way of having an external wireless Magic Keyboard set to a different input source (language layout) than the MacBook's integrated keyboard?

MacBook pro (16-inch 2019) w/Norwegian keyboard language

macOS Monterey 12.1

Magic Keyboard with Numeric Keypad (without Touch ID) w/British keyboard language

I would like to to have the integrated keyboard permanently set to Norwegian input source, and the external Magic Keyboard permanently set to British input source — not having to tap the fn key whenever physically switching between the to keyboards (something I constantly forget, and it halts me every time).

Are there any setting I haven't found, or Terminal command, or third party app that could solve this issue? Having the different keyboards locked to their physical language layout would be a marvelous experience for me.

In hopes that a solution exist

Kindest regards

Alexander
