No, have you considered not running proprietary malware on your computer?;

Due to the endless flow of exploits found, unless you run out and buy new hardware every 2 years, a computer *will* have speculative execution vulnerabilities no matter what proprietary software updates you install.
Regardless, the futility installing proprietary malware to try to fix the problems caused by installing proprietary malware is doomed to utter failure.

All of such hardware only runs with proprietary software currently.
