Well, I got little further. I was able to get the EDL tool to work, but neither the included sdm662 loader nor the one @downeaster59 uploaded work for my Note Air2 Plus.

If I run:

python edl r boot_a boot.img --memory=ufs --loader 0014d0e100000000_d40eee56f3194665_FHPRG.bin

I get:

Qualcomm Sahara / Firehose Client V3.60 (c) B.Kerler 2018-2022.
main - Using loader 0014d0e100000000_d40eee56f3194665_FHPRG.bin ...
main - Waiting for the device
