I don't think there is anyone using the monitoring of phosphor-fan-presence with the control of phosphor-pid-control, but that doesn't mean it can't be done.

If you look at the phosphor-fan recipe you'll see that the default PACKAGECONFIG is "presence control monitor".  I think you'll want to bbappend this to only enable "monitor" (and not control/presence).  This should configure the package so only the monitoring parts are enabled at compile time.

You may want to cc the MAINTAINERS of phosphor-fan-presence for any detailed questions you run into when giving this a try (and copy the list).
