Is it possible to automate the visibility settings of PCB components in KiCad using a Python script?
Yes, automating the visibility settings of PCB components in KiCad can be done using a Python script. The script provided allows you to programmatically set component values to be hidden while keeping their references visible:

```python
#!/usr/bin/env python2.7
import sys
from pcbnew import *

filename=sys.argv[1]

pcb = LoadBoard(filename)
for module in pcb.GetModules():
    print "* Module: %s"%module.GetReference()
    module.Value().SetVisible(False)      # set Value as Hidden
    module.Reference().SetVisible(True)   # set Reference as Visible

pcb.Save("mod_"+filename)
```

This method is particularly helpful for managing the display of numerous components in complex PCB designs, ensuring that the layout remains readable and uncluttered.
