You can try to install chromeOS Flex. In order to install chromeOS Flex (or windows/linux) on an EOL chromebook, you would need to update some firmware.
See
https://mrchromebox.tech. The X131e shows as a
supported model.
I run chromeOS Flex on a 2011 Macbook Air which has direct chromeOS Flex support. It works fine and receives updates.
