It will push updates to the SBAT variable. This variable is used by Non-Windows bootloaders (mostly Linux distributions) by blocking boot of systems that contain boot-related software with known vulnerabilities.

When you never use Linux (including Linux-based recovery tools), you can safely push it. If you use them, check to have the latest version of those media.

Also, when you have a dual-boot scenario, Linux will take care of keeping your SBAT up to date, so you do not need to push it from Windows.
