I have a 12.9" Pro (previous model) and have a pencil 2. Sometimes, it switches to the mini keyboard and becomes stuck on the mini keyboard. Pinch/expand doesn't make it full size. Drag to bottom won't make it full size - it just "bounces" off the bottom like it's not allowed to be too close to it. There is nothing in Settings to switch it back. Closing and reopening apps doesn't work. Locking and unlocking doesn't work. The only thing that works is a full on reboot of the iPad. It will go back to full size where it will stay until I do whatever mistake it is that causes the mini keyboard to reappear.
Everything I've found by searching says to pinch/expand or drag to bottom. I've found nothing for how to resolve when those don't work or, even better, just permanently disable that mini floating keyboard (this seems to not be possible).
