although i could be wrong, i doubt that iNat is doing any Canvas fingerprinting. it just happens that the process to prepare and send an image to be evaluated by the computer vision on the web upload page is similar to the process used by folks doing Canvas fingerprinting. although it’s possible in this case to use a different workflow for the CV here, it would require some tradeoffs and effort that likely don’t outweigh the benefits.
turning off features in your browser in an attempt to prevent tracking has always come at a cost of potentially breaking websites. you should be able to disable Canvas fingerprinting blocking for particular domains or particular webpages. or you could disable it altogether. so you just have to decide whether using iNat computer vision suggestions in the web upload screen is more valuable to you than trying to block potential Canvas fingerprinting there. CV suggestions after upload use a different workflow. so if you need CV suggestions, you should be able to get them just fine on other pages on the site.
