Stop auto-builds?

I see on my cPanel v74.0.12 server that PHP gets automatically upgraded. For example phpinfo() says Build Date: Dec 10 2018 17:17:38. This seems to happen separately from WHM updates to 74.0.x. I'm worried this will break one day. Is there a way to manually turn off these auto-updates/builds and manually trigger them in WHM when I want?
