iPadOS 18 Notes - How do I turn off spell check for handwriting?

I used to love writing with the calligraphy pen in Notes on the iPad and using design elements to convey what I feel. Having annoying lines under words the OS doesn't recognize pop up, go away, and pop up again makes what was a very relaxing activity considerably less so and litters up the page. This would be a great feature in some cases and one I would use, but I have never seen a spell check that can't be disabled. Can I really not disable the spell check for handwriting here? I am only supposed to use Notes one way?
