E120 and Seatalk NG Alarm

I have a E120 (Classic) MFD interfaced to a Maretron Engine monitoring system (EMS100) using NMEA 2000/ SeaTalkNG. The E120 has SW Version 5.69. At low engine speeds while in gear, I get occasional Engine (SeaTalk) alarms on the E120. There is not an engine problem, might just be the oil pressure going below alarm limit threshold.
Is there a way to disable the Seatalk alarms on the E120?
I have set the SeaTalk Alarms to ‘OFF’ in the system menu, but the alarm described above still occur.
