Does Dell XPS 15 9520 supports 2x4TB SSDs?

AI overview: "In terms of storage capacity, the XPS 15 9520 supports a maximum of 4TB SSD storage. While this suggests that a single 4TB SSD is supported, the feasibility of installing two 4TB SSDs (totaling 8TB) is not explicitly confirmed in the available information. However, some users have successfully installed two SSDs, with one being a 1TB or 2TB drive."

I have already successfully installed one 4TB SSD using the first M.2 slot but can I add another 4TB SSD to the second M.2 slot?
