How to avoid this annoying screen? (Already tried unchecking the boot picker)

I’m using OpenCore Legacy Patcher with iMac 2012: everything works great. Just a question: how to automatically boot from SSD 1TB avoiding this screen? If I wait a little bit in here, it will then auto boot from the first macOS disk instead of SSD 1TB and that's what I don't want.

Yes, in settings menu I tried to turn off boot picker and reinstall open core again: nothing happens and I still have this initial screen every time: frustrating.

Also, I have just 2 disks, I’m wondering why the picker is showing 3 options…
