How to Add Airspeed Driver MS4525 while locally compiling for Omnibus F4 Nano V6

I can see in the hwdef.dat file the drivers are set to the minimal set for that board. What I cannot see is how I can override that for this particular airspeed driver.

I cannot use the custom builder as I also need to do custom resource mapping.

Can anyone give me a pointer as to how to do this – I do not need step by step guidance- just pointed in the right direction. Thanks

Edit. Is this the code I need to alter in ardupilot/AP_Airspeed_MS4525.h at d808133aedc39a650a2492cd01da07a4b76b3df7 · ArduPilot/ardupilot · GitHub
