Ch’ello!
I had the same issue with my use of the space bar while using One Note. After playing around with a few keyboard settings on both my MacBook (Monterey v12.4) and iPad (v15.5) I was able to prevent the space bar from focusing on Search; but I still had to use the Shift key to get a space in text. Then I found something that fixed it.
My Fix:
In your iPad settings go to Accessibility>Keyboards>Full Access Keyboards (on)>Commands. Scroll down in the Commands modal until you see the Interaction section (3rd from the top). The first listed command is ‘Activate’. I had an active command in there; so I just cleared the keyboard assignment and ¡voila! FIXED
