So, like I was originally asking... I guess "amixer -c0 set Beep 0% mute" is ok 
in rc.local, but I'd prefer to not even have the device.

$ udevadm info --query=all 
--path=/sys/devices/pci0000\:00/0000\:00\:1b.0/input/input7/
P: /devices/pci0000:00/0000:00:1b.0/input/input7
E: UDEV_LOG=3
E: DEVPATH=/devices/pci0000:00/0000:00:1b.0/input/input7
E: PRODUCT=1/111d/7605/1
E: NAME="HDA Digital PCBeep"
E: PHYS="card0/codec#0/beep0"

I tried creating 00-custom.rules and 99-custom.rules in /etc/udev/rules.d

SUBSYSTEM=="input" NAME=="HDA Digital PCBeep" OPTIONS+="ignore_device"

I also tried = and == for OPTIONS. But the device is still showing up. Is there 
some Arch specific rule overriding this?
