CS Service Request Is it recommended to update DFF without going through the API

I am going to introduce a DFF in Service Requests form in Depot Repair (CS_INCIDENTS_VL_SEC table)

And I need to get the records in that table out and whenevr the record is obtained form the process I need to update a flag to 'Y' in this table to flag the record has been fetched and in future I will select records with DFF value <>'Y'

So I need to update the flag and the question is is it recommended to update the flag with UPDATE statement through Concurrent request, without invoking an API.
