Let’s Encrypt root certificate expiration

I’ve got an old 2011 Mac book pro running os 10.11. Now many websites give me a privacy error due to the root certificate expiration. Not sure if I can update to os 10.12 or later to fix or not. Having trouble finding that in the App Store. Thoughts?

Back up your data, check your applications for compatibility, and click on High Sierra.
