I know that Dublin uses SMR, but do any other airports in Ireland use it?

The wording of this IAA information implies that it's Dublin only:
The IAA also operate an Advanced Surface Movement Guidance and Control System (ASMGCS), which facilitates the safe movement of aircraft and airport vehicles at Dublin Airport, even during poor visibility conditions. The ASMGCS incorporates Surface Movement Radar, Multilateration and ADS-B.
There's a similar comment in this document. And the AIP entry for Dublin mentions surface radar in the obstacles list, but the entries for Cork and Shannon (the next busiest airports) don't.
