Deposit stimulus check electronically without signatures?

We went through the process of moving, and now I can’t find the stimulus check.

I did take pictures of the check before moving, but the check doesn’t have our signatures.

Since my bank lets me deposit electronically by sending them pictures of the check, is it possible to deposit the check by sending those pictures even though it doesn’t have my signature? Or are the signatures and the "For deposit only" required for the bank to deposit it?
