No, these are fixed functions. They operate with the default program that is set on the computer for that function.

Make sure that the keyboard is supporting this layout (e.g. you have a keyboard with a UK layout and you would like to use it on your TV with a German (DE) layout. In this case, the characters on the screen will not correspond with the keyboard.) your TV is supporting this language and language is selected in your smart TV as an input language(s).

The steps to change the language layout vary per TV brand / model.
You can usually find this in the settings on your TV, such as:
Menu -System > Device Manager > Keyboard settings > Options Keyboard > Keyboard Language
However, per brand / model, the above naming can be different.

See an example of how to set the input language layout correctly for a Samsung Smart TV on YouTube.
