Is it possible to dock the split keyboard to the bottom of the screen?

I enjoy that there is the split keyboard option for easy thumbs-only typing, but I am finding myself unable to dock the split keyboard to the bottom of the screen. Is this possible? (to clarify, I do not mean return the split keyboard to the non-split, "docked" position. I am asking whether it can remain split and be docked)

I find it ruins the functionality of the split keyboard to have it getting in the way and hovering over top of whatever I'm trying to read. The worst offender I've found so far is using it in iMessage.
