How do I install a custom firmware that supports KProbes to my Lenovo Flex 5 without installing a new OS?

I have a Lenovo Flex 5, and I’m perfectly happy with ChromeOS, but a few of the apps I want to install require KProbes. After a bit of searching, I found that apparently you have to install custom firmware that supports it. My issue is that I want to keep ChromeOS, but everything I’ve found from my time searching seems to replace my OS with another one. Is there a way I can keep ChromeOS and enable KProbes support?
