+   Then locate the built-in kernel driver and rename it so it cannot be loaded.
+   Renaming allows the original driver to be restored later if needed.

+   /lib/modules/6.6.31+rpt-rpi-2712/kernel/drivers/media/pci/hailo/hailo_pci.ko.xz

+
+   Save the module path to a variable:
+

+   BUILTIN=$(modinfo -n hailo_pci)
