ASUS B860M with two 32GB large-BAR GPUs

Does anyone know if the ASUS B860M can handle two large BAR GPUs? I am considering a couple build options with this motherboard, but do not not have it in hand and before getting it and buying two large GPUs, hoping someone might have experience? Considering B70s (no ReBar option as I understand), V100s, 170HX, etc. I read that some times BAR > 4GB has issues with both cards registering as available?
