That patches chromedriver, (which gets renamed to uc_driver), but patching by itself isn't enough to bypass bot-detection. SeleniumBase also sets specific Chrome options and modifies methods to use the Chrome Devtools Protocol.
I was more astonished that you could just search and replace a string in a PE/ELF binary without breaking everything, but I take your solution over recompiling chrome anytime. Awesome job, very well done!
