AN515-57-79U4 (NH.QEUSA.001) -- Support for PCIE4 M.2 NVME SSDs and Thunderbolt 4 via USB-C?

Hi all,

I recently purchased an Acer Nitro 5 gaming laptop (specifically, the AN515-57-79U4/NH.QEUSA.001). Initial research (based on manufacturer data sheets, retailer product listings, and user reports) indicated that both PCIE4 M.2 NVME SSDs and Thunderbolt 4 via USB-C are supported. However, this doesn't appear to be the case, as there are no Thunderbolt 4 related options within the BIOS (even after updating to the latest version of 1.14) or Windows device manager. Could someone please confirm whether both the primary and secondary M.2 slots support the installation of PCIE4 M.2 NVME SSDs (i.e. aren't limited to PCIE3 bandwidth) and if the USB-C slot has support for Thunderbolt 4? The absence of either would be a dealbreaker, but the latter would be baffling, as it's present on the inexpensive AN515-57 models.

After performing additional testing, I can confirm that the AN515-57-79U4/NH.QEUSA.001 does NOT support Thunderbolt 4 or DisplayPort Alternate Mode via USB-C. Hence, the display configuration is limited to a single external display via HDMI. The absence of this functionality is quite baffling, as it's present on the less expensive AN515-57-54ZA/NH.QDGSA.002. The inconsistency between models within the same product family and the overall ambiguity of the data sheets is quite appalling, and is seemingly creating confusion for both retailers and consumers.
