I don't know. That question likely is a very rare one.
You could always give the funds to relatives, friends, donate it to charity, your church, your fire department (based on your profile name), etc. When they spend it, it would help the economy.
You said "stimulus check." Or are you asking if you can get an electronic direct deposit instead of a check?
