Just need some clarification on your question. How do you know this is a driver?
Process control is typically achieved with some variation of the launchctl command:
The above link is pretty good at detailing the service list. Let me know if that helps.
Driver control is a bit different. The driver equivalent on macOS is a kernel extension (kext). Are you able to try the following?
# get root access
sudo bash -
# Attempt to unload kext
kextload | grep -i DRIVER_NAME
This should unload the driver. You can then force replace it in /System/Library/Extensions or whatever directory it resides in. Then do the following:
# fix permissions
sudo chmod -R 755 /path/to/name.kext
sudo chown -R root:wheel /path/to/name.kext
# Attempt to load driver
kextload -v DRIVER_NAME
Some more information would be key, but this is the general procedure I would follow.
PROCEED AT YOUR OWN RISK!!
