Is there a way to have double keyboard on ASUS Zen 2 phone?

[AC Question]

How to find, install and operate it?

If you mean an on-screen keyboard, I've never seen a double one. Why would you want one? You can only type a key on one at a time, and they'd both be feeding the same app.

Do you mean having two keyboard apps installed? You can install another keyboard app like Google Keyboard and change current keyboard from ASUS keyboard to Google keyboard in Apps>Settings>Language & Input.
