Amazon Linux 2 is a Linux distribution that is designed to be highly compatible with Red Hat Enterprise Linux (RHEL) and offers long-term support, security updates, and performance enhancements. The Linux kernel is the core component of the operating system that manages the system's resources and provides an interface for other software to interact with the hardware. This product has associated charges for the support provided and the Pre-configured stack.

As of February 2023, the latest version of Amazon Linux 2 uses the Linux kernel version 4.14. The version of the Linux kernel that is used can affect the performance, stability, and compatibility of the operating system, so it is important to keep it up-to-date with security patches and bug fixes.

That being said, it is possible to install a different version of the Linux kernel on Amazon Linux 2, including version 5.10, which is a Long Term Support (LTS) release of the kernel. However, doing so requires some technical knowledge and may not be supported by Amazon Web Services (AWS), the provider of Amazon Linux 2.

If you are considering installing a different kernel version, it is recommended to consult the documentation and support resources provided by the Linux distribution or the vendor of the software that requires a specific kernel version to ensure that the new kernel is compatible with your system and software.
