Stream is going to continue to get the same kernel that RHEL gets, it's just going to get updates earlier. In the past, users with binary 3rd party drivers would need to wait a while after a point release before they could update their kernel. In CentOS Stream, they'll have to wait a while after a kernel package update before they can update their kernel. There's really very little changing, here. The point releases are going away, so the date of kernel updates is less predictable, but the solution hasn't changed at all: If you use a binary 3rd party kernel module, you need a process in place to block kernel updates until your 3rd party kernel modules are available.
