No correct, you can't give guarantees but I would at least like to see some proof in tests that it performs better than anti-malware tools without causing any side effects. And yes, it's probably a better idea if you can only disable it via the BIOS, but I did read that an app will be able to interact with SSD-Insider++, not sure if it will give you an option to enable/disable protection.
There will never be a 100% solution - hardware or software based - against malware. They're tools nothing more and their effectiveness rests with the human beings who use them. We are the weak link in computing security no matter what cybersecurity firms may come up with.
