Hmm wrong way round if you have vibration area you need to clamp
together connections, and provide shock absorbing mounts for the board. Elastic band will allow movement opposite of what you want, movement means intermittent connections
Suggest you find a way to clamp SD card to socket or have some insulating stiff material hold the SD card down. Not
glue SD card down, but something over the SD card socket to hold the SD card down.
Rubber feet glued to board is minimum of shock mount I would do, consider what the engine mounting blocks in a car are bolts through a thick stiff rubber block.
