2019 M550i How to tune back to stock?

I currently own a 2019 BMW M550i that has been fitted with a custom ECU tune from RK Tunes. I am now looking to revert the vehicle back to its original factory configuration. I am in possession of the stock ECU files; however, the software previously used for tuning is no longer functional or supported.

Could anyone recommend a reliable and compatible software solution that would allow me to flash the stock files back onto the ECU? or if it can be done remotely ?
