vMix to ATEM Streaming Bridge

Has anyone discovered a way to send an RTMP stream to the Streaming Bridge that's not via an ATEM Mini? All I'd like to do is send my vMix RTMP out via the internet to a remote location, with the Streaming Bridge acting as an RTMP receiving server. It's a simple process and I use a software solution currently, but the Streaming Bridge does not currently facilitate what would be the perfect hardware solution.
I have seen the YT videos for OBS and Restream code solutions to stream to the SB, neither of which provides a solution for vMix.
