They have their own nn,etc libraries so adapting should be fairly focused and AMD drivers have a hilariously bad reputation historically among people who program GPU's (I've been bitten a couple of times myself by weirdness).
I think you should consider it as, if they're trying to avoid Nvidia and make sure their code isn't tied to NVidia-isms, and AMD is troublesome enough for basics the step to customized solutions is small enough to be worthwhile for something even cheaper than AMD.
