Is there a keyboard app for Android with T9 but autocomplete disabled?

Question

Android

Good day to all!
I have been using devices on Android OS for several years now, and for several years I have been suffering with keyboards and their choice. Essence of the question:
You need a keyboard (application), standard QWERTY / YTSUKENG, with auto-replacement (the same T9 that allows you to miss the keys) but with auto-completion of words and phrases that can be turned off. That is, so that she would offer me options in which the number of letters strictly coincides with the ones I have already entered .
An example of how all keyboards do what I tried: I enter "prmz" (FOUR letters), and the keyboard, by pressing "enter" or "space", replaces this with "have to"(since this is the first autocorrect option on her list). I need to automatically replace (and suggest) the first nearest word of exactly FOUR letters , or not change or suggest at all, and not as it is implemented now - the word jester knows how many letters, if only it was in the dictionary.
I hope I didn't explain too chaotically.
Thanks in advance for your replies.
