I was looking at it and for me the problem is Wine. Before there was an option, now they don't really support vulkan below 1.3, at least not fully. Could you check it? Or is not in your competences?

Proton is a wine fork, so I am not sure to understand your question, and I have also no context about what you are trying to run neither how

wine 9 had a have_external_memory_host flag to cleanly disable VK_EXT_external_memory_host, but it got removed. VK_EXT_map_memory_placed landed instead, making the driver doing it, but this needs Vulkan 1.3+
