So, my command came from Radxa's website on the installation instructions for the SATA hat!

No warnings that I can see about "this will overwrite the useful part of your disk...."
Looks to me like six of one, half a dozen of the other.
No, that link doesn't mention the destructive effects of that dd command. On the other hand if you were following their instructions from the start your OS would have been on a micro SD card and the target drive unformatted.
Best to treat it as a lesson learned (don't run any commands unless you understand what they do). I suspect the data you have overwritten is gone for good* other parts of the drive may be recoverable but yu'll need the correct tools to do that.
*: If the drive wasn't full, put the writes to unused cells, remapped them, hasn't erased the old cells and you have apropriate really low level tools to acess the drive (the sort that gets into the firmware and reads the raw data not the mapped blocks) you might have a chance. But it won;t be quick, easy, or cheap. If your SSD supports access at the level in the first place.
