Welcome, @DJohn.16​, to the community!
Even though the STM32L496VGT6 included in the kit has a dual bank read-while-write Flash, an auto-upgrade of the firmware would require a special bootloader that supports this and of course a data source including the connection to it from which the upgrade can be obtained. However, the source code for the kit is not available, so you can only upgrade manually.
Does it answer your question?
