No PX Kernel modules for AWS

When deploying Portworx on top of Ubuntu 22.04 in AWS, Portworx 3.0.0 fails to initialize due to no compatible PX kernel module being available:
Failed to load PX filesystem dependencies for kernel 5.19.0-1028-aws

Checking the source location ( there are kernel modules for azure and gcp there, but not for aws.
Why are these missing?
