Our participants are able to submit offline cash and check donations in their Participant Center, but we don't want these gifts flowing to Luminate CRM. Is it possible to prevent them from syncing?
By confirming the offline donations, it is an acknowledgement that you received the money and therefore is a real donation, which will sync to LCRM. There is no way to change this behavior. as a workaround, you can create a donation form that is not cross referenced and accepts cash and check donations. Then the participants can use that form instead. By doing this, it may cause your numbers to be different between LO and LCRM.
