How hard would it be to add 10 GbE to the Aoostar WTR Pro NAS

I really like the Aoostar WTR Pro NAS, but wish it had 10 GbE instead of 2.5.  I would run TrueNAS and ideally want to use the two NVMe SSD M.2 Gen 3x4 slots for SSDs.  This would leave the smaller M.2 slot open.  I realize that due to lane restrictions, the I may not get the full 10 GbE bandwidth, but would still get greater than 2.5 GbE speeds. What would then be my max throughput in this scenario? I don't mind a hacky solution that would require leaving the bottom ventilation plate removed from the system.  If this is too crazy, is using a 5 GbE external USB dongle an option to get higher throughput without resorting to lagging the two 2.5 GbE interfaces? If so, which one would work best?
