Think little different. If the accounting entry will not generate, then will your FI balance be matched ?
At the time of 351 movement type you have some accounting entry, but at the time scrapping you want to post it without accounting entry.
Its like you have purchased a material with price, but you want to sale it without price. It should not allowed in any business process(and its SAP, a strong business process). It is very harmful for your balance sheet and P/L statement.
SAP will never allow that.
