Open sys.txt which is in \iGO_Luna main folder and modify paragraph [keyboard].

For example in order to hide all Keyboards except ENGLISH QWERTY, GREEK and GREEK QWERTY, I used the below syntax in Keyboard paragraph:

[keyboard]
skip_panels="qwertz,azerty,abcd,arabic,hebrew,hebrew_qwerty,thai,hiragana,hiragana_qwerty,pinyin,vietnamese,turkish_q,turkish_f,arabic,Hungarian,russian,Hungarian mobil,Ukrainian Number"

Spoiler: Available Keyboards
