Hi Inbaraj , I understand that you have explored on one of amazon linux instance which had a 5.15 kernel but you are not able to see the modules that are enabled.Please correct me if I misunderstood.

Amazon Linux 2 does not have NVMe_TCP modules yet.

I would recommend you submit a ticket with amazon Premium Support on this link[1] concerning enabling these modules as well as submitting a feature request for the modules to be included and enabled by default in the future releases of Amazon Linux 2

I would also advise you to keep an eye on what’s new for future releases on this link [2]
