No. The QMID is required by law. This law was updated in 2021 or 2022, and specified that for all products installed after Dec 31, 2024, the credit would only be allowed if the manufacturer gets "qualified" (by entering an agreement with the IRS) and assigning a unique ID number to each qualifying product. Companies had 2 or 3 years to get on board. If your manufacturer chose not to get on board, you have to take it up with them.
